4.6 Input/Output Registers
The AWU shares registers with the keyboard interrupt (KBI) module and the port A I/O module. The
following I/O registers control and monitor operation of the AWU:
Port A data register (PTA)
Keyboard interrupt status and control register (KBSCR)
Keyboard interrupt enable register (KBIER)
4.6.1 Port A I/O Register
The port A data register (PTA) contains a data latch for the state of the AWU interrupt request, in addition
to the data latches for port A.
Address: $0000

AWUL — Auto Wakeup Latch
This is a read-only bit which has the value of the auto wakeup interrupt request latch. The wakeup
request signal is generated internally. There is no PTA6 port or any of the associated bits such as
PTA6 data direction or pullup bits.
1 = Auto wakeup interrupt request is pending
0 = Auto wakeup interrupt request is not pending
PTA5–PTA0 bits are not used in conjuction with the auto wakeup feature.
To see a description of these bits, see
4.6.2 Keyboard Status and Control Register
The keyboard status and control register (KBSCR):
Flags keyboard/auto wakeup interrupt requests
Acknowledges keyboard/auto wakeup interrupt requests
Masks keyboard/auto wakeup interrupt requests
Address: $001A
