Interrupt Request 0 Register

Reserved
For all interrupts other than the WDT interrupt, 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
(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 IRQ0
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.
