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).
