The Interrupt Edge Select (IRQES) register
generated for the rising edge or falling edge on the selected GPIO Port input pin. The
Interrupt Port Select register selects between Port A and Port D for the individual inter-
rupts.
IESx—Interrupt Edge Select x
The minimum pulse width should be greater than 1 system clock to guarantee capture of
the edge triggered interrupt. Shorter pulses may be captured but not guaranteed.
0 = An interrupt request is generated on the falling edge of the PAx/PDx input.
1 = An interrupt request is generated on the rising edge of the PAx/PDx input.
where x indicates the specific GPIO Port pin number (0 through 7).
The Port Select (IRQPS) register
PAx/PDx interrupts. This register allows either Port A or Port D pins to be used as
interrupts. The Interrupt Edge Select register controls the active interrupt edge.
