4.6.3 Keyboard Interrupt Enable Register
MC68HC908QF4 — Rev. 1.0
MOTOROLA
NOTE:
NOTE:
ACKK — Keyboard Acknowledge Bit
IMASKK— Keyboard Interrupt Mask Bit
MODEK is not used in conjuction with the auto wakeup feature. To see a
description of this bit, see
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
KBIE5–KBIE0 bits are not used in conjuction with the auto wakeup feature. To see
a description of these bits, see
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.
Address: $001B
This read/write bit enables the auto wakeup interrupt input to latch interrupt
requests. Reset clears AWUIE.
Reset:
Read:
Write:
1 = Keyboard/auto wakeup interrupt requests masked
0 = Keyboard/auto wakeup interrupt requests not masked
1 = Auto wakeup enabled as interrupt input
0 = Auto wakeup not enabled as interrupt input
