Low Power Modes
3.9.2 Stop 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.
3.10 Low-Voltage Inhibit Module (LVI)
3.10.1 Wait Mode
If enabled, the LVI module remains active in wait mode. If enabled to
generate resets, the LVI module can generate a reset and bring the MCU
out of wait mode.
3.10.2 Stop Mode
If enabled, the LVI module remains active in stop mode. If enabled to
generate resets, the LVI module can generate a reset and bring the MCU
out of stop mode.
3.11 Serial Communications Interface Module (SCI)
3.11.1 Wait Mode
The SCI module remains active in wait mode. Any enabled CPU
interrupt request from the SCI module can bring the MCU out of wait
mode.
If SCI module functions are not required during wait mode, reduce power
consumption by disabling the module before executing the WAIT
instruction.
