PA7I—Port A7
0 = No interrupt request is pending for GPIO Port A.
1 = An interrupt request from GPIO Port A.
PA6CI—Port A6 or comparator interrupt request
0 = No interrupt request is pending for GPIO Port A or comparator.
1 = An interrupt request from GPIO Port A or comparator.
PAxI—Port A Pin x interrupt request
0 = No interrupt request is pending for GPIO Port A pin x.
1 = An interrupt request from GPIO Port A pin x is awaiting service.
where x indicates the specific GPIO port pin number (0–5).
The interrupt request 2 (IRQ2) register stores interrupt requests for both vectored and
polled interrupts. See
corresponding bit in the IRQ2 register becomes 1. If interrupts are globally enabled
(vectored interrupts), the interrupt controller passes an interrupt request to the eZ8 CPU. If
interrupts are globally disabled (polled interrupts), the eZ8 CPU reads the interrupt request
2 register to determine if any interrupt requests are pending.
Reserved—Must be 0.
PCxI—Port C pin x interrupt request
0 = No interrupt request is pending for GPIO Port C pin x.
1 = An interrupt request from GPIO Port C pin x is awaiting service.
where x indicates the specific GPIO Port C pin number (0–3).
