Interrupt Request 1 Register
Description (Continued)
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.
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.
Reserved
These bits are reserved and must be programmed to 00.
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.
Description
Port A Pin 7 or LVD Interrupt Request
0 = No interrupt request is pending for GPIO Port A or LVD.
1 = An interrupt request from GPIO Port A or LVD.
Port A Pin 6 or Comparator Interrupt Request
0 = No interrupt request is pending for GPIO Port A or Comparator.
1 = An interrupt request from GPIO Port A or Comparator.
Port A Pin x Interrupt Request
0 = No interrupt request is pending for GPIO Port A pin x.
1 = An interrupt request from GPIO Port A pin x is awaiting service.

The Interrupt Request 1 (IRQ1) Register, shown in Table 36, stores interrupt requests for
both vectored and polled interrupts. When a request is presented to the interrupt controller,
the 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 can read the Interrupt
Request 1 Register to determine if any interrupt requests are pending.
