For all interrupts other than the Watchdog Timer interrupt, the Primary Oscillator Fail
Trap, and the Watchdog Timer Oscillator Fail Trap, the interrupt control registers enable
individual interrupts, set interrupt priorities, and indicate interrupt requests.
The Interrupt Request 0 (IRQ0) register
vectored and polled interrupts. When a request is presented to the interrupt controller, the
corresponding bit in the IRQ0 register becomes 1. If interrupts are globally enabled (vec-
tored 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 0 register to determine if any interrupt requests are pending.
Reserved—Must be 0
T1I—Timer 1 Interrupt Request
0 = No interrupt request is pending for Timer 1
1 = An interrupt request from Timer 1 is awaiting service
T0I—Timer 0 Interrupt Request
0 = No interrupt request is pending for Timer 0
1 = An interrupt request from Timer 0 is awaiting service
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
ADCI—ADC Interrupt Request
0 = No interrupt request is pending for the ADC
1 = An interrupt request from the ADC is awaiting service
