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.
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 stores interrupt requests for both vectored and
polled interrupts. See
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 interrupt request
1 register to determine if any interrupt requests are pending.
