MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER FUNCTIONAL DESCRIPTION CENTRAL PROCESSING UNIT (CPU) [Stack Pointer (S)] The stack pointer is an 8-bit register used during subroutine calls and interrupts. This register indicates start address of stored area (stack) for storing registers during subroutine calls and interrupts. The low-order 8 bits of the stack address are determined by the contents of the stack pointer.

MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER [Processor status register (PS)] The processor status register is an 8-bit register consisting of 5 flags which indicate the status of the processor after an arithmetic operation and 3 flags which decide MCU operation. Branch operations can be performed by testing the Carry (C) flag , Zero (Z) flag, Overflow (V) flag, or the Negative (N) flag. In decimal mode, the Z, V, N flags are not valid.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER [CPU Mode Register (CPUM)] 003B16 The CPU mode register contains the stack page selection bit and the internal system clock selection bit. The CPU mode register is allocated at address 003B16.

MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER INTERRUPTS Interrupt Operation Interrupts occur by seventeen sources: eight external, eight internal, and one software. By acceptance of an interrupt, the following operations are automatically performed: 1. The contents of the program counter and the processor status register are automatically pushed onto the stack. 2. The interrupt disable flag is set and the corresponding interrupt request bit is cleared. 3.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER When not requiring for the interrupt occurrence synchronized with these setting, take the following sequence. ➀Set the corresponding interrupt enable bit to “0” (disabled). ➁Set the interrupt edge select bit or the interrupt source select bit to “1”. ➂Set the corresponding interrupt request bit to “0” after 1 or more instructions have been executed. ➃Set the corresponding interrupt enable bit to “1” (enabled).
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Key Input Interrupt (Key-on Wake Up) A Key-on wake up interrupt request is generated by applying a falling edge to any pin of port P2 that have been set to input mode. In other words, it is generated when AND of input level goes from “1” to “0”.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER TIMERS Read and write operation on 16-bit timer must be performed for both high- and low-order bytes. When reading a 16-bit timer, read the high-order byte first. When writing to a 16-bit timer, write the low-order byte first. The 16-bit timer cannot perform the correct operation when reading during the write operation, or when writing during the read operation.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timer X Timer X is a 16-bit timer that can be selected in one of four modes and can be controlled the timer X write and the real time port by setting the timer X mode register. (1) Timer mode The timer counts f(XIN)/16 (or f(XCIN)/16 in low-speed mode). (2) Pulse output mode Each time the timer underflows, a signal output from the CNTR 0 pin is inverted.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timer Y Timer Y is a 16-bit timer that can be selected in one of four modes. (1) Timer mode The timer counts f(XIN)/16 (or f(XCIN)/16 in low-speed mode). (2) Period measurement mode CNTR 1 interrupt request is generated at rising/falling edge of CNTR1 pin input signal. Simultaneously, the value in timer Y latch is reloaded in timer Y and timer Y continues counting down.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timer 1, Timer 2, Timer 3 Timer 1, timer 2, and timer 3 are 8-bit timers. The count source for each timer can be selected by timer 123 mode register. The timer latch value is not affected by a change of the count source. However, because changing the count source may cause an inadvertent count down of the timer. Therefore, rewrite the value of timer whenever the count source is changed.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER SERIAL I/O (1) Clock Synchronous Serial I/O Mode Serial I/O can be used as either clock synchronous or asynchronous (UART) serial I/O. A dedicated timer (baud rate generator) is also provided for baud rate generation. Clock synchronous serial I/O mode can be selected by setting the mode selection bit of the serial I/O control register to “1”.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER ter, but the two buffers have the same address in memory. Since the shift register cannot be written to or read from directly, transmit data is written to the transmit buffer, and receive data is read from the receive buffer. The transmit buffer can also hold the next data to be transmitted, and the receive buffer register can hold a character while the next character is being received.
MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER [Transmit Buffer/Receive Buffer Register (TB/ RB)] 001816 The transmit buffer register and the receive buffer register are located at the same address. The transmit buffer register is writeonly and the receive buffer register is read-only. If a character bit length is 7 bits, the MSB of data stored in the receive buffer register is “0”.

MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER A-D CONVERTER Comparator and Control Circuit The functional blocks of the A-D converter are described below. The comparator and control circuit compare an analog input voltage with the comparison voltage and store the result in the A-D conversion register. When an A-D conversion is completed, the control circuit sets the AD conversion completion bit and the AD interrupt request bit to “1”.

LCD display RAM Segment output enable register LCD mode register Voltage multiplier Selector Timing controller Common driver Segment driver Bias control circuit A maximum of 40 segment output pins and 4 common output pins can be used. Up to 160 pixels can be controlled for LCD display.

MITSUBISHI MICROCOMPUTERS 3825 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER RESET CIRCUIT To reset the microcomputer, RESET pin should be held at an “L” level for 2 µs or more. Then the RESET pin is returned to an “H” level (the power source voltage should be between VCC(min.) and 5.5 V, and the quartz-crystal oscillator should be stable), reset is released. After the reset is completed, the program starts from the address contained in address FFFD16 (high-order byte) and address FFFC 16 (low-order byte).
