PA7VI—Port A7 or LVD Interrupt Request
0 = No interrupt request is pending for GPIO Port A7 or LVD.
1 = An interrupt request from GPIO Port A7 or LVD.
PA6CI—Port A6 or Comparator 0 Interrupt Request
0 = No interrupt request is pending for GPIO Port A6 or Comparator 0.
1 = An interrupt request from GPIO Port A6 or Comparator 0.
PA5CI—Port A5 or Comparator 1 Interrupt Request
0 = No interrupt request is pending for GPIO Port A5 or Comparator 1.
1 = An interrupt request from GPIO Port A5 or Comparator 1.
PADxI—Port A or Port D Pin x Interrupt Request
0 = No interrupt request is pending for GPIO Port A or Port D pin x.
1 = An interrupt request from GPIO Port A or Port D pin x is awaiting service.
Where x indicates the specific GPIO Port pin number (1–4).
PA0I—Port A Pin 0 Interrupt Request
0 = No interrupt request is pending for GPIO Port A0.
1 = An interrupt request from GPIO Port A0 is awaiting service.
For interrupt source select description, see
The Interrupt Request 2 (IRQ2) register
requests for both vectored and polled interrupts. When a request is presented to the
interrupt controller, the 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 can
read the Interrupt Request 2 register to determine if any interrupt requests are pending.
Reserved—Must be 0
MCTI—Multi-channel timer Interrupt Request
0 = No interrupt request is pending for multi-channel timer.
1 = An interrupt request from multi-channel timer is awaiting service.
U1RXI—UART 1 Receiver Interrupt Request
0 = No interrupt request is pending for the UART 1 receiver.
1 = An interrupt request from the UART 1 receiver is awaiting service.
