KBIE5–KBIE0 — Port A Keyboard Interrupt Enable Bits
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.
1 = KBIx pin enabled as keyboard interrupt pin
0 = KBIx pin not enabled as keyboard interrupt pin
NOTE
AWUIE bit is not used in conjunction with the keyboard interrupt feature. To
see a description of this bit, see Chapter 4 Auto Wakeup Module (AWU).
