Keyboard Interrupt Module (KBI)
9.7.2 Keyboard Interrupt Enable Register
The port A keyboard interrupt enable register (KBIER) enables or disables each port A pin or auto wakeup
to operate as a keyboard interrupt input.
KBIE5–KBIE0 — Port A Keyboard Interrupt Enable Bits
84
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
Address: $001B
AWUIE bit is not used in conjunction with the keyboard interrupt feature. To
