Interrupt Control Register Definitions  
For all interrupts other than the Watch-Dog Timer interrupt, the interrupt control registers  
enable individual interrupts, set interrupt priorities, and indicate interrupt requests.  
Interrupt Request 0 Register  
The Interrupt Request 0 (IRQ0) register (Table 23) stores the interrupt requests for both  
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 can read the Interrupt  
Request 0 register to determine if any interrupt requests are pending

T2I—Timer 2 Interrupt Request  
0 = No interrupt request is pending for Timer 2.  
1 = An interrupt request from Timer 2 is awaiting service.  
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.
