Address:
The keyboard interrupt enable register enables or disables each port A
pin 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.
The keyboard interrupt module remains active in stop mode. Clearing
the IMASKK bit in the keyboard status and control register enables
keyboard interrupt requests to bring the MCU out of stop 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.
