Interrupt Port Select register selects between Port A and Port D for the individual inter-
rupts.
IESx—Interrupt Edge Select x
where x indicates the specific GPIO Port pin number (0 through 7). The pulse width
should be greater than 1 system clock to guarantee capture of the edge triggered interrupt.
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.
The Port Select (IRQPS) register (Table 36) determines the port pin that generates the
PAx/PDx interrupts. This register allows either Port A or Port D pins to be used as inter-
rupts. The Interrupt Edge Select register controls the active interrupt edge.
PADxS—PAx/PDx Selection
0 = PAx is used for the interrupt for PAx/PDx interrupt request.
1 = PDx is used for the interrupt for PAx/PDx interrupt request.
where x indicates the specific GPIO Port pin number (0 through 7).
