Address:
When bit DDRAx is a logic 1, reading address $0000 reads the PTAx
data latch. When bit DDRAx is a logic 0, reading address $0000 reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
the operation of the port A pins.
The keyboard interrupt enable register (KBIER) selects the port A pins
for keyboard interrupt function or as standard I/O function. (See
21. Keyboard Interrupt Module

Notes:
Reset:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.

Setting a KBIEx bit to logic 1 configures the PTAx/KBIx pin for
keyboard interrupt function. Reset clears the KBIEx bits.
