The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The keyboard 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 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.
Two registers control and monitor operation of the keyboard module:
The keyboard status and control register (KBSCR):
•
