PADxENH—Port A or Port D Bit[x] Interrupt Request Enable High Bit.
For selection of either Port A or Port D as the interrupt source, see
Register
PADxENL—Port A or Port D Bit[x] Interrupt Request Enable Low Bit
For selection of either Port A or Port D as the interrupt source, see
Register
The IRQ2 Enable High and Low Bit registers (see
a priority encoded enabling for interrupts in the Interrupt Request 2 register. Priority is
generated by setting bits in each register.
