I2CI— I2C Interrupt Request  
0 = No interrupt request is pending for the I2C.  
1 = An interrupt request from the I2C is awaiting service.  
SPII—SPI Interrupt Request  
0 = No interrupt request is pending for the SPI.  
1 = An interrupt request from the SPI 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.  
Interrupt Request 1 Register  
The Interrupt Request 1 (IRQ1) register (Table 24) 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.

PADxI—Port A or Port D Pin x Interrupt Request  
0 = No interrupt request is pending for GPIO Port A or Port D pin x.  
1 = An interrupt request from GPIO Port A or Port D pin x is awaiting service.  
where x indicates the specific GPIO Port pin number (0 through 7). For each pin, only 1 of  
either Port A or Port D can be enabled for interrupts at any one time. Port selection (A or  
D) is determined by the values in the Interrupt Port Select Register.
