The interrupt edge select (IRQES) register determines whether an interrupt is generated
for the rising edge or falling edge on the selected GPIO Port A or Port D input pin. See
Table
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 or PDx.
where x indicates the specific GPIO port pin number (0 through 7).
The shared interrupt select (IRQSS) register determines the source of the PADxS
interrupts. See
Port A and alternate sources for the individual interrupts.
