IESx—Interrupt Edge Select x
0 = An interrupt request is generated on the falling edge of the PAx input or PDx
1 = An interrupt request is generated on the rising edge of the PAx input PDx
where x indicates the specific GPIO port pin number (0 through 7)
The Shared Interrupt Select (IRQSS) register
PADxS interrupts. The Shared Interrupt Select register selects between Port A and
alternate sources for the individual interrupts.
Because these shared interrupts are edge-triggered, it is possible to generate an interrupt
just by switching from one shared source to another. For this reason, an interrupt must be
disabled before switching between sources.
PA6CS—PA6/Comparator Selection
0 = PA6 is used for the interrupt for PA6CS interrupt request
1 = The Comparator is used for the interrupt for PA6CS interrupt request
Reserved—Must be 0
The Interrupt Control (IRQCTL) register
interrupts.
