Interrupt Request 2 Register
Note:
Description
PADxI – Port A/D Pin x Interrupt Request
0 = No interrupt request is pending for GPIO port A/D pin x.
1 = An interrupt request from GPIO port A/D pin x is awaiting service. Writing 1 to these bits
resets them to 0.
Here x indicates the specific GPIO port pin number (0 through 7). PAD7I and PAD0I have inter-
rupt sources other than Port A and Port D as selected by the Port A Irq Mux registers. PAD7I is
configured to provide the comparator interrupt. PAD0I is configured to provide the OCD inter-
rupt.

These bits are set any time the selected port is toggled. The setting of these bits are not
affected by the associated interrupt enable bits.
The interrupt request 2 (IRQ2) Register (see Table 34) stores interrupt requests for both
vectored and polled interrupts. When a request is presented to the interrupt controller, the
corresponding bit in the IRQ2 Register becomes 1. If interrupts are globally enabled (vec-
tored interrupts), the interrupt controller passes an interrupt request to the CPU. If inter-
rupts are globally disabled (polled interrupts), the CPU reads the Interrupt Request 1
Register to determine, if any interrupt requests are pending. Writing 1 to the bits in this
register clears the interrupt. The bits of this register are set by writing 1 to the interrupt
request 2 set regsiter (IRQ2SET) at address
