Auto Wakeup Module (AWU)
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
MODEK is not used in conjuction with the auto wakeup feature. To see a
description of this bit, see
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.
Address: $001B

Figure 4-4. Keyboard Interrupt Enable Register (KBIER)
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
KBIE5–KBIE0 bits are not used in conjuction with the auto wakeup feature.
To see a description of these bits, see
Register.
