PIC16C5X 3.0 ARCHITECTURAL OVERVIEW The high performance of the PIC16C5X family can be attributed to a number of architectural features commonly found in RISC microprocessors. To begin with, the PIC16C5X uses a Harvard architecture in which program and data are accessed on separate buses. This improves bandwidth over traditional von Neumann architecture where program and data are fetched on the same bus.

PIC16C5X 3.1 Clocking Scheme/Instruction Cycle 3.2 Instruction Flow/Pipelining An Instruction Cycle consists of four Q cycles (Q1, Q2, Q3 and Q4). The instruction fetch and execute are pipelined such that fetch takes one instruction cycle, while decode and execute takes another instruction cycle. However, due to the pipelining, each instruction effectively executes in one cycle. If an instruction causes the program counter to change (e.g.

PIC16C5X 4.0 OSCILLATOR CONFIGURATIONS 4.1 Oscillator Types FIGURE 4-2: PIC16C5Xs can be operated in four different oscillator modes. The user can program two configuration bits (FOSC1:FOSC0) to select one of these four modes: 1. 2. 3. 4. LP: XT: HS: RC: Note: 4.
PAGE 16
PIC16C5X 4.3 External Crystal Oscillator Circuit Either a prepackaged oscillator or a simple oscillator circuit with TTL gates can be used as an external crystal oscillator circuit. Prepackaged oscillators provide a wide operating range and better stability. A welldesigned crystal oscillator will provide good performance with TTL gates. Two types of crystal oscillator circuits can be used: one with parallel resonance, or one with series resonance. Figure 4-4 shows a series resonant oscillator circuit.
PAGE 17
PIC16C5X 4.4 FIGURE 4-5: RC Oscillator For timing insensitive applications, the RC device option offers additional cost savings. The RC oscillator frequency is a function of the supply voltage, the resistor (REXT) and capacitor (CEXT) values, and the operating temperature. In addition to this, the oscillator frequency will vary from unit to unit due to normal process parameter variation.

PIC16C5X 5.0 RESET The TO and PD bits (STATUS <4:3>) are set or cleared depending on the different RESET conditions (Table 51). These bits may be used to determine the nature of the RESET. PIC16C5X devices may be RESET in one of the following ways: • • • • • Power-On Reset (POR) MCLR Reset (normal operation) MCLR Wake-up Reset (from SLEEP) WDT Reset (normal operation) WDT Wake-up Reset (from SLEEP) Table 5-3 lists a full description of RESET states of all registers.

PIC16C5X 5.1 FIGURE 5-2: Power-On Reset (POR) The PIC16C5X family incorporates on-chip Power-On Reset (POR) circuitry which provides an internal chip RESET for most power-up situations. To use this feature, the user merely ties the MCLR/VPP pin to VDD. A simplified block diagram of the on-chip Power-On Reset circuit is shown in Figure 5-1. The Power-On Reset circuit and the Device Reset Timer (Section 5.2) circuit are closely related. On power-up, the RESET latch is set and the DRT is RESET.

PIC16C5X 5.2 FIGURE 5-7: Device Reset Timer (DRT) The Device Reset Timer (DRT) provides an 18 ms nominal time-out on RESET regardless of Oscillator mode used. The DRT operates on an internal RC oscillator. The processor is kept in RESET as long as the DRT is active. The DRT delay allows VDD to rise above VDD min., and for the oscillator to stabilize. Oscillator circuits based on crystals or ceramic resonators require a certain time after power-up to establish a stable oscillation.

PIC16C5X 6.0 MEMORY ORGANIZATION FIGURE 6-2: PIC16C5X memory is organized into program memory and data memory. For devices with more than 512 bytes of program memory, a paging scheme is used. Program memory pages are accessed using one or two STATUS Register bits. For devices with a data memory register file of more than 32 registers, a banking scheme is used. Data memory banks are accessed using the File Selection Register (FSR).
PAGE 26
PIC16C5X 6.2 FIGURE 6-4: Data Memory Organization Data memory is composed of registers, or bytes of RAM. Therefore, data memory for a device is specified by its register file. The register file is divided into two functional groups: Special Function Registers and General Purpose Registers.

PAGE 28
PIC16C5X 6.2.2 SPECIAL FUNCTION REGISTERS The Special Function Registers are registers used by the CPU and peripheral functions to control the operation of the device (Table 6-1). The Special Registers can be classified into two sets. The Special Function Registers associated with the “core” functions are described in this section. Those related to the operation of the peripheral features are described in the section for each peripheral feature.
PAGE 29
PIC16C5X 6.3 STATUS Register writable. Therefore, the result of an instruction with the STATUS Register as destination may be different than intended. This register contains the arithmetic status of the ALU, the RESET status and the page preselect bits for program memories larger than 512 words. For example, CLRF STATUS will clear the upper three bits and set the Z bit. This leaves the STATUS Register as 000u u1uu (where u = unchanged).
PAGE 30
PIC16C5X 6.4 OPTION Register The OPTION Register is a 6-bit wide, write-only register which contains various control bits to configure the Timer0/WDT prescaler and Timer0. By executing the OPTION instruction, the contents of the W Register will be transferred to the OPTION Register. A RESET sets the OPTION<5:0> bits.
PAGE 31
PIC16C5X 6.5 FIGURE 6-8: Program Counter As a program instruction is executed, the Program Counter (PC) will contain the address of the next program instruction to be executed. The PC value is increased by one, every instruction cycle, unless an instruction changes the PC. GOTO Instruction PC For a GOTO instruction, bits 8:0 of the PC are provided by the GOTO instruction word. The PC Latch (PCL) is mapped to PC<7:0> (Figure 6-7, Figure 6-8 and Figure 6-9).
PAGE 32
PIC16C5X 6.5.1 PAGING CONSIDERATIONS – PIC16C56/CR56, PIC16C57/CR57 AND PIC16C58/CR58 If the Program Counter is pointing to the last address of a selected memory page, when it increments it will cause the program to continue in the next higher page. However, the page preselect bits in the STATUS Register will not be updated. Therefore, the next GOTO, CALL or modify PCL instruction will send the program to the page specified by the page preselect bits (PA0 or PA<1:0>).
PAGE 33
PIC16C5X 6.7 EXAMPLE 6-2: Indirect Data Addressing; INDF and FSR Registers The INDF Register is not a physical register. Addressing INDF actually addresses the register whose address is contained in the FSR Register (FSR is a pointer). This is indirect addressing.

PIC16C5X 7.0 I/O PORTS 7.5 As with any other register, the I/O Registers can be written and read under program control. However, read instructions (e.g., MOVF PORTB,W) always read the I/O pins independent of the pin’s input/output modes. On RESET, all I/O ports are defined as input (inputs are at hi-impedance) since the I/O control registers (TRISA, TRISB, TRISC) are all set. 7.1 PORTA PORTA is a 4-bit I/O Register. Only the low order 4 bits are used (RA<3:0>).
PAGE 36
PIC16C5X 7.6 7.6.1 EXAMPLE 7-1: I/O Programming Considerations BI-DIRECTIONAL I/O PORTS READ-MODIFY-WRITE INSTRUCTIONS ON AN I/O PORT Some instructions operate internally as read followed by write operations. The BCF and BSF instructions, for example, read the entire port into the CPU, execute the bit operation and re-write the result. Caution must be used when these instructions are applied to a port where one or more pins are used as input/outputs.
PAGE 37
PIC16C5X 8.0 TIMER0 MODULE AND TMR0 REGISTER Counter mode is selected by setting the T0CS bit (OPTION<5>). In this mode, Timer0 will increment either on every rising or falling edge of pin T0CKI. The incrementing edge is determined by the source edge select bit T0SE (OPTION<4>). Clearing the T0SE bit selects the rising edge. Restrictions on the external clock input are discussed in detail in Section 8.1.

PAGE 39
PIC16C5X 8.1 Using Timer0 with an External Clock When a prescaler is used, the external clock input is divided by the asynchronous ripple counter-type prescaler so that the prescaler output is symmetrical. For the external clock to meet the sampling requirement, the ripple counter must be taken into account. Therefore, it is necessary for T0CKI to have a period of at least 4TOSC (and a small RC delay of 40 ns) divided by the prescaler value.
PAGE 40
PIC16C5X 8.2 EXAMPLE 8-1: Prescaler An 8-bit counter is available as a prescaler for the Timer0 module, or as a postscaler for the Watchdog Timer (WDT), respectively (Section 9.2.1). For simplicity, this counter is being referred to as “prescaler” throughout this data sheet. Note that the prescaler may be used by either the Timer0 module or the WDT, but not both. Thus, a prescaler assignment for the Timer0 module means that there is no prescaler for the WDT, and vice-versa.

PIC16C5X 9.0 SPECIAL FEATURES OF THE CPU What sets a microcontroller apart from other processors are special circuits that deal with the needs of realtime applications. The PIC16C5X family of microcontrollers have a host of such features intended to maximize system reliability, minimize cost through elimination of external components, provide power saving operating modes and offer code protection. These features are: • • • • • • • • Oscillator Selection (Section 4.0) RESET (Section 5.
PAGE 44
PIC16C5X 9.1 Configuration Bits Configuration bits can be programmed to select various device configurations. Two bits are for the selection of the oscillator type and one bit is the Watchdog Timer enable bit. Nine bits are code protection bits for the PIC16C54A, PIC16CR54A, PIC16C54C, PIC16CR54C, PIC16C55A, PIC16C56A, PIC16CR56A, PIC16C57C, PIC16CR57C, REGISTER 9-1: CP CP PIC16C58B, and PIC16CR58B devices (Register 9-1).

PIC16C5X 9.2 Watchdog Timer (WDT) both. Thus, a prescaler assignment for the Timer0 module means that there is no prescaler for the WDT, and vice-versa. The Watchdog Timer (WDT) is a free running on-chip RC oscillator which does not require any external components. This RC oscillator is separate from the RC oscillator of the OSC1/CLKIN pin. That means that the WDT will run even if the clock on the OSC1/CLKIN and OSC2/CLKOUT pins have been stopped, for example, by execution of a SLEEP instruction.
PAGE 47
PIC16C5X 9.3 Power-Down Mode (SLEEP) 9.4 A device may be powered down (SLEEP) and later powered up (Wake-up from SLEEP). 9.3.1 SLEEP The Power-down mode is entered by executing a SLEEP instruction. If enabled, the Watchdog Timer will be cleared but keeps running, the TO bit (STATUS<4>) is set, the PD bit (STATUS<3>) is cleared and the oscillator driver is turned off. The I/O ports maintain the status they had before the SLEEP instruction was executed (driving high, driving low, or hi-impedance).
