3.3
When the RES pin goes low, all processing halts and this LSI enters the reset. The internal state of
the CPU and the registers of the on-chip peripheral modules are initialized by the reset. To ensure
that this LSI is reset at power-up, hold the RES pin low until the clock pulse generator output
stabilizes. To reset the chip during operation, hold the RES pin low for at least 10 system clock
cycles. When the RES pin goes high after being held low for the necessary time, this LSI starts
reset exception handling. The reset exception handling sequence is shown in figure 3.1.
The reset exception handling sequence is as follows:
1. Set the I bit in the condition code register (CCR) to 1.
2. The CPU generates a reset exception handling vector address (from H'0000 to H'0001), the

There are external interrupts, NMI, IRQ3 to IRQ0, and WKP5 to WKP0.
(1)
NMI interrupt is requested by input signal edge to pin NMI. This interrupt is detected by either
rising edge sensing or falling edge sensing, depending on the setting of bit NMIEG in IEGR1.
NMI is the highest-priority interrupt, and can always be accepted without depending on the I bit
value in CCR.
(2)
IRQ3 to IRQ0 interrupts are requested by input signals to pins IRQ3 to IRQ0. These four
interrupts are given different vector addresses, and are detected individually by either rising edge
sensing or falling edge sensing, depending on the settings of bits IEG3 to IEG0 in IEGR1.
When pins IRQ3 to IRQ0 are designated for interrupt input in PMR1 and the designated signal
edge is input, the corresponding bit in IRR1 is set to 1, requesting the CPU of an interrupt. When
IRQ3 to IRQ0 interrupt is accepted, the I bit is set to 1 in CCR. These interrupts can be masked by
setting bits IEN3 to IEN0 in IENR1.
data in that address is sent to the program counter (PC) as the start address, and program
execution starts from that address.
