Auto Wakeup Module (AWU)
4.6.2 Keyboard Status and Control Register
The keyboard status and control register (KBSCR):
Bits 7–4 — Not used
KEYF — Keyboard Flag Bit
ACKK — Keyboard Acknowledge Bit
IMASKK— Keyboard Interrupt Mask Bit
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.

These read-only bits always read as 0s.
This read-only bit is set when a keyboard interrupt is pending on port A or auto wakeup. Reset clears
the KEYF 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.
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 pending
0 = No keyboard/auto wakeup interrupt pending
1 = Keyboard/auto wakeup interrupt requests masked
0 = Keyboard/auto wakeup interrupt requests not masked
Flags keyboard/auto wakeup interrupt requests
Acknowledges keyboard/auto wakeup interrupt requests
Masks keyboard/auto wakeup interrupt requests
