As the external interrupts, there are NMI, IRQ3 to IRQ0, and WKP5 to WKP0 interrupts.
NMI Interrupt
IRQ3 to IRQ0 Interrupts
WKP5 to WKP0 Interrupts
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.
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.
These interrupts can be masked by setting bits IEN3 to IEN0 in IENR1.
WKP5 to WKP0 interrupts are requested by input signals to pins WKP5 to WKP0. These six
interrupts have the same vector addresses, and are detected individually by either rising edge
sensing or falling edge sensing, depending on the settings of bits WPEG5 to WPEG0 in
IEGR2.
When pins WKP5 to WKP0 are designated for interrupt input in PMR5 and the designated
signal edge is input, the corresponding bit in IWPR is set to 1, requesting the CPU of an
interrupt. These interrupts can be masked by setting bit IENWP in IENR1.
