Freescale Semiconductor
Bits 7–4 — Not used
These read-only bits always read as 0s.
KEYF — Keyboard Flag Bit
This read-only bit is set when a keyboard interrupt is pending on port A or auto wakeup. Reset clears
the KEYF bit.
1 = Keyboard/auto wakeup interrupt pending
0 = No keyboard/auto wakeup interrupt pending
ACKK — Keyboard Acknowledge Bit
Writing a 1 to this write-only bit clears the keyboard/auto wakeup interrupt request on port A and auto
wakeup logic. ACKK always reads as 0.Reset clears ACKK.
IMASKK— Keyboard Interrupt Mask Bit
Writing a 1 to this read/write bit prevents the output of the keyboard interrupt mask from generating
interrupt requests on port A or auto wakeup. Reset clears the IMASKK bit.
1 = Keyboard/auto wakeup interrupt requests masked
0 = Keyboard/auto wakeup interrupt requests not masked
NOTE
MODEK is not used in conjuction with the auto wakeup feature. To see a
description of this bit, see 9.7.1 Keyboard Status and Control Register.
4.6.3 Keyboard Interrupt Enable Register
The keyboard interrupt enable register (KBIER) enables or disables the auto wakeup to operate as a
keyboard/auto wakeup interrupt input.
AWUIE — Auto Wakeup Interrupt Enable Bit
This read/write bit enables the auto wakeup interrupt input to latch interrupt requests. Reset clears
AWUIE.
1 = Auto wakeup enabled as interrupt input
0 = Auto wakeup not enabled as interrupt input
NOTE
KBIE5–KBIE0 bits are not used in conjuction with the auto wakeup feature.
To see a description of these bits, see 9.7.2 Keyboard Interrupt Enable
Register.
