9.6.2 Keyboard Interrupt Enable Register
The keyboard interrupt enable register (KBIER) enables or disables each port A pin to operate as a
keyboard interrupt pin.
KBIE4–KBIE0 — Keyboard Interrupt Enable Bits
Each of these read/write bits enables the corresponding keyboard interrupt pin to latch interrupt
requests. Reset clears the keyboard interrupt enable register.
1 = PAx pin enabled as keyboard interrupt pin
0 = PAx pin not enabled as keyboard interrupt pin
