Rev. 2.1
Address:
The keyboard interrupt enable register individually enables or disables
the PTA0/KBI0–PTA3/KBI3 and PTD4/KBI4–PTD7/KBI7 pins to operate
as a keyboard interrupt pin.
KBIE7–KBIE0 — Keyboard Interrupt Enable Bits
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The keyboard interrupt module remains active in wait mode. Clearing the
IMASKK bit in the keyboard status and control register enables keyboard
interrupt requests to bring the MCU out of wait mode.
Reset:
Read:
Write:
Each of these read/write bits enables the corresponding keyboard
interrupt pin to latch interrupt requests. Reset clears the keyboard
interrupt enable register.
