20.7.1 Wait Mode
20.7.2 Stop Mode
20.8 Keyboard Module During Break Interrupts
Data Sheet
414
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.
The system integration module (SIM) controls whether the keyboard
interrupt latch can be cleared during the break state. The BCFE bit in the
SIM break flag control register (BFCR) enables software to clear status
bits during the break state.
To allow software to clear the keyboard interrupt latch during a break
interrupt, write a logic 1 to the BCFE bit. If a latch is cleared during the
break state, it remains cleared when the MCU exits the break state.
To protect the latch during the break state, write a logic 0 to the BCFE
bit. With BCFE at logic 0 (its default state), writing to the keyboard
acknowledge bit (ACKK) in the keyboard status and control register
during the break state has no effect.
