MITSUBISHI MICROCOMPUTERS 3822 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 3822 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER responding to that timer is set to “1”. 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 3822 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(X CIN)/16 in low-speed mode). (2) Pulse Output Mode Each time the timer underflows, a signal output from the CNTR0 pin is inverted.

(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 3822 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, rewrite the value of timer whenever the count source is changed.
MITSUBISHI MICROCOMPUTERS 3822 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 can be selected by setting the mode selection bit of the serial I/O control register to “1”. For clock synchronous serial I/O, the transmitter and the receiver must use the same clock.
MITSUBISHI MICROCOMPUTERS 3822 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.

After a reset, initialize flags which affect program execution. In particular, it is essential to initialize the index X mode (T) and the decimal mode (D) flags because of their effect on calculations.
MITSUBISHI MICROCOMPUTERS 3822 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER NOTES ON USE Countermeasures against noise Noise (1) Shortest wiring length ➀ Wiring for RESET pin Make the length of wiring which is connected to the RESET pin as short as possible. Especially, connect a capacitor across the RESET pin and the VSS pin with the shortest possible wiring (within 20mm). ● Reason The width of a pulse input into the RESET pin is determined by the timing necessary conditions.
MITSUBISHI MICROCOMPUTERS 3822 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER (3) Oscillator concerns In order to obtain the stabilized operation clock on the user system and its condition, contact the oscillator manufacturer and select the oscillator and oscillation circuit constants. Be careful especially when range of votage and temperature is wide. Also, take care to prevent an oscillator that generates clocks for a microcomputer operation from being affected by other signals.
