PA7VI—Port A7 Interrupt Request
0 = No interrupt request is pending for GPIO Port A
1 = An interrupt request from GPIO Port A or LVD.
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 (Table 36) stores interrupt requests for both vec-
tored and polled interrupts. When a request is presented to the interrupt controller, the cor-
responding 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 can read 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).
