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 Analog-to-Digital Converter.
1 = An interrupt request from the Analog-to-Digital Converter is awaiting service.
The Interrupt Request 1 (IRQ1) register (Table 33) stores interrupt requests for both vec-
tored and polled interrupts. When a request is presented to the interrupt controller, the cor-
responding 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 can read the Interrupt Request 1
register to determine if any interrupt requests are pending.
