The port A keyboard interrupt enable register (KBIER) enables or
disables each port A pin or auto wake-up to operate as a keyboard
interrupt input.

AWUIE — Auto Wake-up Interrupt Enable Bit
Reset:
Read:
Write:
Each of these read/write bits enables the corresponding keyboard
interrupt pin on port A to latch interrupt requests. Reset clears the
keyboard interrupt enable register.
This read/write bit enables the auto wake-up interrupt input to latch
interrupt requests. Reset clears AWUIE.
