Interrupt Request 2 Register

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 (0 through 7). For each pin, only 1 of
either Port A or Port D can be enabled for interrupts at any one time. Port selection (A or
D) is determined by the values in the Interrupt Port Select Register.
The Interrupt Request 2 (IRQ2) register
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 1
register to determine if any interrupt requests are pending.
T3I—Timer 3 Interrupt Request
0 = No interrupt request is pending for Timer 3.
1 = An interrupt request from Timer 3 is awaiting service.
U1RXI—UART 1 Receive Interrupt Request
0 = No interrupt request is pending for the UART1 receiver.
1 = An interrupt request from UART1 receiver is awaiting service.
U1TXI—UART 1 Transmit Interrupt Request
0 = No interrupt request is pending for the UART 1 transmitter.
1 = An interrupt request from the UART 1 transmitter is awaiting service.
DMAI—DMA Interrupt Request
0 = No interrupt request is pending for the DMA.
1 = An interrupt request from the DMA is awaiting service.
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.
