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).
The Interrupt Control (IRQCTL) register
interrupts.
IRQE—Interrupt Request Enable
This bit is set to 1 by execution of an EI or IRET instruction, or by a direct register write of
a 1 to this bit. It is reset to 0 by executing a DI instruction, eZ8 CPU acknowledgement of
an interrupt request, or Reset.
0 = Interrupts are disabled
1 = Interrupts are enabled
Reserved—Must be 0.
