Comparator A generates an interrupt request from two sources, comparator A1 and comparator A2. Non-maskable
or maskable can be selected for each interrupt type.
Refer to 11. Interrupts for details of interrupts.
When the COMPSEL bit in the CMPA register is set to 1 (bits IRQ1SEL and IRQ2SEL enabled) and the
IRQiSEL (i = 1 or 2) is set to 0, the comparator Ai interrupt functions as a non-maskable interrupt.
When the selected interrupt request timing occurs, the VWiC2 bit in the VWiC register is set to 1. At this time,
a non-maskable interrupt request for comparator Ai is generated.
When the COMPSEL bit in the CMPA register is set to 1 (bits IRQ1SEL and IRQ2SEL enabled) and the
IRQiSEL (i = 1 or 2) is set to 1, the comparator Ai interrupt functions as a maskable interrupt.
The comparator Ai interrupt uses the corresponding VCMPiIC register (bits IR and ILVL0 to ILVL2) and a
single vector. When the selected interrupt request timing occurs, the VWiC2 bit in the VWiC register is set to 1.
At this time, the IR bit in the VCMPiIC register is set to 1 (interrupt requested).
Refer to 11.3 Interrupt Control for the VCMPiIC register and 11.1.5.2 Relocatable Vector Tables for
interrupt vectors.
