9.8 Keyboard Interrupt Module (KBI)
9.8.1 Wait Mode
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.
9.8.2 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.
9.9 Low-Voltage Inhibit Module (LVI)
9.9.1 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.
9.9.2 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.
9.10 Serial Communications Interface Module (SCI)
9.10.1 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.
9.10.2 Stop Mode
The SCI module is inactive in stop mode. The STOP instruction does not affect SCI
register states. SCI module operation resumes after the MCU exits stop mode.
Because the internal clock is inactive during stop mode, entering stop mode during
an SCI transmission or reception results in invalid data.
