Interrupt Request 1 Register

PA7I
U0RXI—UART 0 Receiver Interrupt Request
0 = No interrupt request is pending for the UART 0 receiver.
1 = An interrupt request from the UART 0 receiver is awaiting service.
U0TXI—UART 0 Transmitter Interrupt Request
0 = No interrupt request is pending for the UART 0 transmitter.
1 = An interrupt request from the UART 0 transmitter is awaiting service.
I 2 CI— I
0 = No interrupt request is pending for the I
1 = An interrupt request from the I
SPII—SPI Interrupt Request
0 = No interrupt request is pending for the SPI.
1 = An interrupt request from the SPI is awaiting service.
ADCI—ADC Interrupt Request
0 = No interrupt request is pending for the ADC.
1 = An interrupt request from the ADC is awaiting service.
The Interrupt Request 1 (IRQ1) Register
vectored and polled interrupts. When a request is presented to the interrupt controller, the
corresponding bit in the IRQ1 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 IRQ1
Register to determine if any interrupt requests are pending.
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 through 7).
