MITSUBISHI MICROCOMPUTERS 38C3 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Key Input Interrupt (Key-on Wake-Up) of using a key input interrupt is shown in Figure 15, where an interrupt request is generated by pressing one of the keys consisted as an active-low key matrix which inputs to ports P80–P8 3. A key input interrupt request is generated by applying “L” level to any pin of port P8 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 38C3 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER TIMERS 8-Bit Timer The 38C3 group has six built-in timers : Timer 1, Timer 2, Timer 3, Timer 4, Timer 5, and Timer 6. Each timer has the 8-bit timer latch. All timers are down-counters. When the timer reaches “0016,” an underflow occurs with the next count pulse. Then the contents of the timer latch is reloaded into the timer and the timer continues down-counting.

MITSUBISHI MICROCOMPUTERS 38C3 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER RESET CIRCUIT Poweron 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 2.5 V and 5.5 V, and the oscillation 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 FFFC16 (low-order byte).
