PIC24FJ64GB004 FAMILY • All VDD and VSS pins (see Section 2.2 “Power Supply Pins”) • All AVDD and AVSS pins, regardless of whether or not the analog device features are used (see Section 2.2 “Power Supply Pins”) • MCLR pin (see Section 2.3 “Master Clear (MCLR) Pin”) • ENVREG/DISVREG and VCAP/VDDCORE pins (PIC24FJ devices only) (see Section 2.
PIC24FJ64GB004 FAMILY 2.2 2.2.1 Power Supply Pins DECOUPLING CAPACITORS The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: • Value and type of capacitor: A 0.1 F (100 nF), 10-20V capacitor is recommended. The capacitor should be a low-ESR device with a resonance frequency in the range of 200 MHz and higher. Ceramic capacitors are recommended.
PIC24FJ64GB004 FAMILY Note: Voltage Regulator Pins (ENVREG/DISVREG and VCAP/VDDCORE) FIGURE 2-3: The on-chip voltage regulator enable/disable pin (ENVREG or DISVREG, depending on the device family) must always be connected directly to either a supply voltage or to ground.
PIC24FJ64GB004 FAMILY 2.6 External Oscillator Pins FIGURE 2-4: Many microcontrollers have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to Section 8.0 “Oscillator Configuration” for details). The oscillator circuit should be placed on the same side of the board as the device. Place the oscillator circuit close to the respective oscillator pins with no more than 0.5 inch (12 mm) between the circuit components and the pins.
PIC24FJ64GB004 FAMILY 2.7 Configuration of Analog and Digital Pins During ICSP Operations If an ICSP compliant emulator is selected as a debugger, it automatically initializes all of the A/D input pins (ANx) as “digital” pins. Depending on the particular device, this is done by setting all bits in the ADnPCFG register(s), or clearing all bit in the ANSx registers. All PIC24F devices will have either one or more ADnPCFG registers or several ANSx registers (one for each port); no device will have both.

PIC24FJ64GB004 FAMILY 3.3.2 DIVIDER 3.3.3 The divide block supports signed and unsigned integer divide operations with the following data sizes: 1. 2. 3. 4. 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The quotient for all divide instructions ends up in W0 and the remainder in W1.
PIC24FJ64GB004 FAMILY 4.0 MEMORY ORGANIZATION As Harvard architecture devices, PIC24F microcontrollers feature separate program and data memory spaces and busses. This architecture also allows the direct access of program memory from the data space during code execution. 4.1 Program Address Space The program address memory space of the PIC24FJ64GB004 family devices is 4M instructions.
PIC24FJ64GB004 FAMILY 4.1.1 PROGRAM MEMORY ORGANIZATION 4.1.3 In PIC24FJ64GB004 family devices, the top four words of on-chip program memory are reserved for configuration information. On device Reset, the configuration information is copied into the appropriate Configuration registers. The addresses of the Flash Configuration Word for devices in the PIC24FJ64GB004 family are shown in Table 4-1. Their location in the memory map is shown with the other memory vectors in Figure 4-1.
PIC24FJ64GB004 FAMILY 4.2 Data Address Space The PIC24F core has a separate, 16-bit wide data memory space, addressable as a single linear range. The data space is accessed using two Address Generation Units (AGUs), one each for read and write operations. The data space memory map is shown in Figure 4-3. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the data space. This gives a data space address range of 64 Kbytes or 32K words.
PIC24FJ64GB004 FAMILY 4.2.2 DATA MEMORY ORGANIZATION AND ALIGNMENT A Sign-Extend (SE) instruction is provided to allow users to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, users can clear the MSB of any W register by executing a Zero-Extend (ZE) instruction on the appropriate address. To maintain backward compatibility with PIC® devices and improve data space memory usage efficiency, the PIC24F instruction set supports both word and byte operations.

PIC24FJ64GB004 FAMILY 4.2.5 4.3 SOFTWARE STACK In addition to its use as a working register, the W15 register in PIC24F devices is also used as a Software Stack Pointer. The pointer always points to the first available free word and grows from lower to higher addresses. It predecrements for stack pops and post-increments for stack pushes, as shown in Figure 4-4. Note that for a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, ensuring that the MSB is always clear.

PIC24FJ64GB004 FAMILY 4.3.2 DATA ACCESS FROM PROGRAM MEMORY USING TABLE INSTRUCTIONS The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the program space without going through data space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a program space word as data. The PC is incremented by two for each successive 24-bit program word.
PIC24FJ64GB004 FAMILY 4.3.3 READING DATA FROM PROGRAM MEMORY USING PROGRAM SPACE VISIBILITY The upper 32 Kbytes of data space may optionally be mapped into any 16K word page of the program space. This provides transparent access of stored constant data from the data space without the need to use special instructions (i.e., TBLRDL/H).
PIC24FJ64GB004 FAMILY NOTES: DS39940D-page 54 2010 Microchip Technology Inc.
PIC24FJ64GB004 FAMILY 5.0 Note: FLASH PROGRAM MEMORY RTSP is accomplished using TBLRD (table read) and TBLWT (table write) instructions. With RTSP, the user may write program memory data in blocks of 64 instructions (192 bytes) at a time and erase program memory in blocks of 512 instructions (1536 bytes) at a time. This data sheet summarizes the features of this group of PIC24F devices. It is not intended to be a comprehensive reference source.
PIC24FJ64GB004 FAMILY 5.2 RTSP Operation The PIC24F Flash program memory array is organized into rows of 64 instructions or 192 bytes. RTSP allows the user to erase blocks of eight rows (512 instructions) at a time and to program one row at a time. It is also possible to program single words. The 8-row erase blocks and single row write blocks are edge-aligned, from the beginning of program memory, on boundaries of 1536 bytes and 192 bytes, respectively.

PIC24FJ64GB004 FAMILY 5.6.1 PROGRAMMING ALGORITHM FOR FLASH PROGRAM MEMORY 4. 5. The user can program one row of Flash program memory at a time. To do this, it is necessary to erase the 8-row erase block containing the desired row. The general process is as follows: 1. 2. 3. Read eight rows of program memory (512 instructions) and store in data RAM. Update the program data in RAM with the desired new data.
PIC24FJ64GB004 FAMILY EXAMPLE 5-2: ERASING A PROGRAM MEMORY BLOCK – ‘C’ LANGUAGE CODE // C example using MPLAB C30 unsigned long progAddr = 0xXXXXXX; unsigned int offset; // Address of row to write //Set up pointer to the first memory location to be written TBLPAG = progAddr>>16; // Initialize PM Page Boundary SFR offset = progAddr & 0xFFFF; // Initialize lower word of address __builtin_tblwtl(offset, 0x0000); // Set base address of erase block // with dummy latch write NVMCON = 0x4042; // Initialize
PIC24FJ64GB004 FAMILY EXAMPLE 5-4: LOADING THE WRITE BUFFERS – ‘C’ LANGUAGE CODE // C example using MPLAB C30 #define NUM_INSTRUCTION_PER_ROW 64 unsigned int offset; unsigned int i; unsigned long progAddr = 0xXXXXXX; unsigned int progData[2*NUM_INSTRUCTION_PER_ROW]; //Set up NVMCON for row programming NVMCON = 0x4001; // Address of row to write // Buffer of data to write // Initialize NVMCON //Set up pointer to the first memory location to be written TBLPAG = progAddr>>16; // Initialize PM Page Boundar
PIC24FJ64GB004 FAMILY 5.6.2 PROGRAMMING A SINGLE WORD OF FLASH PROGRAM MEMORY instructions write the desired data into the write latches and specify the lower 16 bits of the program memory address to write to. To configure the NVMCON register for a word write, set the NVMOP bits (NVMCON<3:0>) to ‘0011’. The write is performed by executing the unlock sequence and setting the WR bit (see Example 5-7).

Select the user-assigned priority level for the interrupt source by writing the control bits in the appropriate IPCx register. The priority level will depend on the specific application and type of interrupt source.
PIC24FJ64GB004 FAMILY 8.
PIC24FJ64GB004 FAMILY 8.1 CPU Clocking Scheme 8.2 The system clock source can be provided by one of four sources: • Primary Oscillator (POSC) on the OSCI and OSCO pins • Secondary Oscillator (SOSC) on the SOSCI and SOSCO pins • Fast Internal RC (FRC) Oscillator • Low-Power Internal RC (LPRC) Oscillator The primary oscillator and FRC sources have the option of using the internal USB PLL block, which generates both the USB module clock and a separate system clock from the 96 MHz PLL. Refer to Section 8.
PIC24FJ64GB004 FAMILY 8.3 Control Registers The operation of the oscillator is controlled by three Special Function Registers (SFRs): • OSCCON • CLKDIV • OSCTUN REGISTER 8-1: The OSCCON register (Register 8-1) is the main control register for the oscillator. It controls clock source switching and allows the monitoring of clock sources. The CLKDIV register (Register 8-2) controls the features associated with Doze mode, as well as the postscaler for the FRC Oscillator.

PIC24FJ64GB004 FAMILY 8.4.2 OSCILLATOR SWITCHING SEQUENCE A recommended code sequence for a clock switch includes the following: At a minimum, performing a clock switch requires this basic sequence: 1. 1. 2. 2. 3. 4. 5. If desired, read the COSCx bits (OSCCON<14:12>) to determine the current oscillator source. Perform the unlock sequence to allow a write to the OSCCON register high byte. Write the appropriate value to the NOSCx bits (OSCCON<10:8>) for the new oscillator source.
PIC24FJ64GB004 FAMILY 8.5 Oscillator Modes and USB Operation TABLE 8-2: Because of the timing requirements imposed by USB, an internal clock of 48 MHz is required at all times while the USB module is enabled. Since this is well beyond the maximum CPU clock speed, a method is provided to internally generate both the USB and system clocks from a single oscillator source.
PIC24FJ64GB004 FAMILY 8.6 8.6.1 Secondary Oscillator (SOSC) BASIC SOSC OPERATION PIC24FJ64GB004 family devices do not have to set the SOSCEN bit to use the secondary oscillator. Any module requiring the SOSC (such as RTCC, Timer1 or DSWDT) will automatically turn on the SOSC when the clock signal is needed. The SOSC, however, has a long start-up time. To avoid delays for peripheral start-up, the SOSC can be manually started using the SOSCEN bit.

PIC24FJ64GB004 FAMILY 9.0 Note: POWER-SAVING FEATURES This data sheet summarizes the features of this group of PIC24F devices. It is not intended to be a comprehensive reference source. For more information, refer to the “PIC24F Family Reference Manual”, Section 39. “Power-Saving Features with Deep Sleep” (DS39727). The PIC24FJ64GB004 family of devices provides the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals.
PIC24FJ64GB004 FAMILY 9.2.2 IDLE MODE Note: Idle mode has these features: • The CPU will stop executing instructions. • The WDT is automatically cleared. • The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 9.4 “Selective Peripheral Module Control”). • If the WDT or FSCM is enabled, the LPRC will also remain active.
PIC24FJ64GB004 FAMILY 9.2.4.2 Special Cases when Entering Deep Sleep Mode When entering Deep Sleep mode, there are certain circumstances that require a delay between setting the DSEN bit and executing the PWRSAV instruction. These can be generally reduced to three scenarios: 1. 2. 3.
PIC24FJ64GB004 FAMILY 9.2.4.3 Exiting Deep Sleep Mode Deep Sleep mode exits on any one of the following events: • POR event on VDD supply. If there is no DSBOR circuit to re-arm the VDD supply POR circuit, the external VDD supply must be lowered to the natural arming voltage of the POR circuit. • DSWDT time-out. When the DSWDT timer times out, the device exits Deep Sleep. • RTCC alarm (if RTCEN = 1). • Assertion (‘0’) of the MCLR pin.
PIC24FJ64GB004 FAMILY Once the device wakes back up, all I/O pins continue to maintain their previous states, even after the device has finished the POR sequence and is executing application code again. Pins configured as inputs during Deep Sleep remain high-impedance and pins configured as outputs continue to drive their previous value. After waking up, the TRIS and LAT registers, and the SOSCEN bit (OSCCON<1>) are reset.
PIC24FJ64GB004 FAMILY 9.2.4.10 Power-on Resets (PORs) 9.2.4.11 Summary of Deep Sleep Sequence VDD voltage is monitored to produce PORs. Since exiting from Deep Sleep functionally looks like a POR, the technique described in Section 9.2.4.9 “Checking and Clearing the Status of Deep Sleep Mode” should be used to distinguish between Deep Sleep and a true POR event.

PIC24FJ64GB004 FAMILY 9.3 Doze Mode Generally, changing clock speed and invoking one of the power-saving modes are the preferred strategies for reducing power consumption. There may be circumstances, however, where this is not practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else.
PIC24FJ64GB004 FAMILY NOTES: DS39940D-page 126 2010 Microchip Technology Inc.
PIC24FJ64GB004 FAMILY 10.0 Note: I/O PORTS When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin may be read, but the output driver for the parallel port bit will be disabled. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port. This data sheet summarizes the features of this group of PIC24F devices.
PIC24FJ64GB004 FAMILY 10.1.1 OPEN-DRAIN CONFIGURATION In addition to the PORT, LAT and TRIS registers for data control, each port pin can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Control register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs higher than VDD (e.g.
PIC24FJ64GB004 FAMILY 10.3 Input Change Notification The input change notification function of the I/O ports allows the PIC24FJ64GB004 family of devices to generate interrupt requests to the processor in response to a change of state on selected input pins. This feature is capable of detecting input Change-of-States (COS) even in Sleep mode, when the clocks are disabled.
PIC24FJ64GB004 FAMILY 10.4.3 CONTROLLING PERIPHERAL PIN SELECT Peripheral Pin Select features are controlled through two sets of Special Function Registers: one to map peripheral inputs and one to map outputs. Because they are separately controlled, a particular peripheral’s input and output (if the peripheral has both) can be placed on any selectable function pin without constraint.
PIC24FJ64GB004 FAMILY 10.4.3.2 Output Mapping the bit field corresponds to one of the peripherals and that peripheral’s output is mapped to the pin (see Table 10-3). In contrast to inputs, the outputs of the Peripheral Pin Select options are mapped on the basis of the pin. In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping.
PIC24FJ64GB004 FAMILY 10.4.3.3 Mapping Limitations 10.4.4.1 The control schema of the Peripheral Pin Select is extremely flexible. Other than systematic blocks that prevent signal contention caused by two physical pins being configured as the same functional input, or two functional outputs configured as the same pin, there are no hardware enforced lock outs.
PIC24FJ64GB004 FAMILY 10.4.5 CONSIDERATIONS FOR PERIPHERAL PIN SELECTION The ability to control Peripheral Pin Selection introduces several considerations into application design that could be overlooked. This is particularly true for several common peripherals that are available only as remappable peripherals. The main consideration is that the Peripheral Pin Selects are not available on default pins in the device’s default (Reset) state.

It is not intended to be a comprehensive reference source. For more information, refer to the “PIC24F Family Reference Manual”, Section 34. “Input Capture with Dedicated Timer” (DS39722). Devices in the PIC24FJ64GB004 family all feature 5 independent input capture modules.
PIC24FJ64GB004 FAMILY 13.1.2 CASCADED (32-BIT) MODE By default, each module operates independently with its own 16-bit timer. To increase resolution, adjacent even and odd modules can be configured to function as a single 32-bit module. (For example, Modules 1 and 2 are paired, as are modules 3 and 4, and so on.) The odd-numbered module (ICx) provides the Least Significant 16 bits of the 32-bit register pairs, and the even module (ICy) provides the Most Significant 16 bits.

PIC24FJ64GB004 FAMILY 14.2 Compare Operations In Compare mode (Figure 14-1), the output compare module can be configured for single-shot or continuous pulse generation; it can also repeatedly toggle an output pin on each timer event. To set up the module for compare operations: 1. 2. 3. 4. 5. 6. 7. Configure the OCx output for one of the available Peripheral Pin Select pins.
PIC24FJ64GB004 FAMILY 14.3 Pulse-Width Modulation (PWM) Mode 5. 6. In PWM mode, the output compare module can be configured for edge-aligned or center-aligned pulse waveform generation. All PWM operations are double-buffered (buffer registers are internal to the module and are not mapped into SFR space). To configure the output compare edge-aligned PWM operation: 1. 2. 3. 4. module 7. 8. for Note: Configure the OCx output for one of the available Peripheral Pin Select pins.
PIC24FJ64GB004 FAMILY 14.3.1 PWM PERIOD 14.3.2 PWM DUTY CYCLE In edge aligned PWM mode, the period is specified by the value of OCxRS register. In center aligned PWM mode, the period of the synchronization source such as Timer's PRy specifies the period. The period in both cases can be calculated using Equation 14-1. The PWM duty cycle is specified by writing to the OCxRS and OCxR registers.
PIC24FJ64GB004 FAMILY 14.4 Subcycle Resolution The DCB bits are intended for use with a clock source identical to the system clock. When an OCx module with enabled prescaler is used, the falling edge delay caused by the DCB bits will be referenced to the system clock period, rather than the OCx module's period. The DCB bits (OCxCON2<10:9>) provide for resolution better than one instruction cycle. When used, they delay the falling edge generated by a match event by a portion of an instruction cycle.

It is not intended to be a comprehensive reference source. For more information, refer to the “PIC24F Family Reference Manual”, ”Section 27. USB On-The-Go (OTG)” (DS39721). PIC24FJ64GB004 family devices contain a full-speed and low-speed compatible, On-The-Go (OTG) USB Serial Interface Engine (SIE).

PIC24FJ64GB004 FAMILY 18.1 Hardware Configuration 18.1.1 DEVICE MODE 18.1.1.1 D+ Pull-up Resistor PIC24FJ64GB004 family devices have a built-in 1.5 k resistor on the D+ line that is available when the microcontroller in operating in device mode. This is used to signal an external Host that the device is operating in Full-Speed Device mode. It is engaged by setting the USBEN bit (U1CON<0>). If the OTGEN bit (U1OTGCON<2>) is set, then the D+ pull-up is enabled through the DPPULUP bit (U1OTGCON<7>).
PIC24FJ64GB004 FAMILY 18.1.2 18.1.2.1 HOST AND OTG MODES microcontroller is running below VBUS and is not able to source sufficient current, a separate power supply must be provided. D+ and D- Pull-down Resistors PIC24FJ64GB004 family devices have built-in 15 k pull-down resistor on the D+ and D- lines. These are used in tandem to signal to the bus that the microcontroller is operating in Host mode. They are engaged by setting the HOSTEN bit (U1CON<3>).
PIC24FJ64GB004 FAMILY 18.1.2.3 VBUS Voltage Generation with External Devices When operating as a USB host, either as an A-device in an OTG configuration or as an embedded host, VBUS must be supplied to the attached device. PIC24FJ64GB004 family devices have an internal VBUS boost assist to help generate the required 5V VBUS from the available voltages on the board.
PIC24FJ64GB004 FAMILY 18.2 USB Buffer Descriptors and the BDT Endpoint buffer control is handled through a structure called the Buffer Descriptor Table (BDT). This provides a flexible method for users to construct and control endpoint buffers of various lengths and configurations. The BDT can be located in any available, 512-byte aligned block of data RAM. The BDT Pointer (U1BDTP1) contains the upper address byte of the BDT, and sets the location of the BDT in RAM.
PIC24FJ64GB004 FAMILY BDs have a fixed relationship to a particular endpoint, depending on the buffering configuration. Table 18-2 provides the mapping of BDs to endpoints. This relationship also means that gaps may occur in the BDT if endpoints are not enabled contiguously. This theoretically means that the BDs for disabled endpoints could be used as buffer space. In practice, users should avoid using such spaces in the BDT unless a method of validating BD addresses is implemented. 18.2.

PIC24FJ64GB004 FAMILY 18.3 USB Interrupts level consists of USB error conditions, which are enabled and flagged in the U1EIR and U1EIE registers. An interrupt condition in any of these triggers a USB Error Interrupt Flag (UERRIF) in the top level. The USB OTG module has many conditions that can be configured to cause an interrupt. All interrupt sources use the same interrupt vector. Interrupts may be used to trap routine events in a USB transaction.
PIC24FJ64GB004 FAMILY 18.3.1 CLEARING USB OTG INTERRUPTS Unlike device level interrupts, the USB OTG interrupt status flags are not freely writable in software. All USB OTG flag bits are implemented as hardware set only bits. Additionally, these bits can only be cleared in FIGURE 18-10: software by writing a ‘1’ to their locations (i.e., performing a MOV type instruction). Writing a ‘0’ to a flag bit (i.e., a BCLR instruction) has no effect.
PIC24FJ64GB004 FAMILY 18.4.2 1. 2. 3. 4. Attach to a USB host and enumerate as described in Chapter 9 of the USB 2.0 specification. Create a data buffer, and populate it with the data to send to the host. In the appropriate (EVEN or ODD) Tx BD for the desired endpoint: a) Set up the status register (BDnSTAT) with the correct data toggle (DATA0/1) value and the byte count of the data buffer. b) Set up the address register (BDnADR) with the starting address of the data buffer.
PIC24FJ64GB004 FAMILY 18.5.2 1. 2. 3. 4. 5. 6. 7. COMPLETE A CONTROL TRANSACTION TO A CONNECTED DEVICE Follow the procedure described in Section 18.5.1 “Enable Host Mode and Discover a Connected Device” to discover a device. Set up the Endpoint Control register for bidirectional control transfers by writing 0Dh to U1EP0 (this sets the EPCONDIS, EPTXEN, and EPHSHK bits). Place a copy of the device framework setup command in a memory buffer. See Chapter 9 of the USB 2.
PIC24FJ64GB004 FAMILY 18.5.3 1. 2. 3. 4. 5. 6. 7. SEND A FULL-SPEED BULK DATA TRANSFER TO A TARGET DEVICE Follow the procedure described in Section 18.5.1 “Enable Host Mode and Discover a Connected Device” and Section 18.5.2 “Complete a Control Transaction to a Connected Device” to discover and configure a device. To enable transmit and receive transfers with handshaking enabled, write 1Dh to U1EP0. If the target device is a low-speed device, also set the LSPD bit (U1EP0<7>).
PIC24FJ64GB004 FAMILY The B-device then proceeds by pulsing the VBUS supply. Software should do this by setting PUVBUS (U1CNFG2<4>). When an A-device detects SRP signaling (either via the ATTACHIF (U1IR<6>) interrupt or via the SESVDIF (U1OTGIR<3>) interrupt), the A-device must restore the VBUS supply by either setting VBUSON (U1OTGCON<3>), or by setting the I/O port controlling the external power source. DPPULUP and DMPULUP.
PIC24FJ64GB004 FAMILY 18.7 USB OTG Module Registers There are a total of 37 memory mapped registers associated with the USB OTG module. They can be divided into four general categories: • • • • USB OTG Module Control (12) USB Interrupt (7) USB Endpoint Management (16) USB VBUS Power Control (2) This total does not include the (up to) 128 BD registers in the BDT. Their prototypes, described in Register 18-1 and Register 18-2, are shown separately in Section 18.2 “USB Buffer Descriptors and the BDT”.

PIC24FJ64GB004 FAMILY 20.3 Calibration The real-time crystal input can be calibrated using the periodic auto-adjust feature. When calibrated, the RTCC can provide an error of less than 3 seconds per month. This is accomplished by finding the number of error clock pulses and storing the value into the lower half of the RCFGCAL register. The 8-bit signed value loaded into the lower half of RCFGCAL is multiplied by four and will either be added or subtracted from the RTCC timer, once every minute.

PIC24FJ64GB004 FAMILY 21.0 Note: 32-BIT PROGRAMMABLE CYCLIC REDUNDANCY CHECK (CRC) GENERATOR The programmable CRC generator provides a hardware-implemented method of quickly generating checksums for various networking and security applications.
PIC24FJ64GB004 FAMILY 21.1 User Interface 21.1.1 POLYNOMIAL INTERFACE The CRC module can be programmed for CRC polynomials of up to the 32nd order, using up to 32 bits. Polynomial length, which reflects the highest exponent in the equation, is selected by the PLEN<4:0> bits (CRCCON2<4:0>). The CRCXORL and CRCXORH registers control which exponent terms are included in the equation.
PIC24FJ64GB004 FAMILY 21.1.3 DATA SHIFT DIRECTION The LENDIAN bit (CRCCON1<3>) is used to control the shift direction. By default, the CRC will shift data through the engine, MSb first. Setting LENDIAN (= 1) causes the CRC to shift data, LSb first. This setting allows better integration with various communication schemes and removes the overhead of reversing the bit order in software. Note that this only changes the direction of the data that is shifted into the engine.

PIC24FJ64GB004 FAMILY 26.2 On-Chip Voltage Regulator All PIC24FJ64GB004 family devices power their core digital logic at a nominal 2.5V. This may create an issue for designs that are required to operate at a higher typical voltage, such as 3.3V. To simplify system design, all devices in the PIC24FJ64GB004 family incorporate an on-chip regulator that allows the device to run its core logic from VDD. The regulator is controlled by the DISVREG pin.
PIC24FJ64GB004 FAMILY When waking up from Sleep mode with the regulator disabled, TPM is used to determine the wake-up time. To decrease the device wake-up time when operating with the regulator disabled, the PMSLP bit can be set. 26.3 26.2.3 The nominal WDT clock source from LPRC is 31 kHz. This feeds a prescaler that can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128) operation. The prescaler is set by the FWPSA Configuration bit.
PIC24FJ64GB004 FAMILY 26.3.1 WINDOWED OPERATION 26.3.2 The Watchdog Timer has an optional Fixed Window mode of operation. In this Windowed mode, CLRWDT instructions can only reset the WDT during the last 1/4 of the programmed WDT period. A CLRWDT instruction is executed before that window causes a WDT Reset; this is similar to a WDT time-out. Windowed WDT mode is enabled by programming the WINDIS Configuration bit (CW1<6>) to ‘0’.
PIC24FJ64GB004 FAMILY 26.5.2 CODE SEGMENT PROTECTION In addition to global General Segment protection, a separate subrange of the program memory space can be individually protected against writes and erases. This area can be used for many purposes where a separate block of erase and write-protected code is needed, such as bootloader applications.
PIC24FJ64GB004 FAMILY 26.6 JTAG Interface PIC24FJ64GB004 family devices implement a JTAG interface, which supports boundary scan device testing. 26.7 In-Circuit Serial Programming PIC24FJ64GB004 family microcontrollers can be serially programmed while in the end application circuit. This is simply done with two lines for clock (PGECx) and data (PGEDx), and three other lines for power, ground and the programming voltage.
