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.
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.
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.
The DMA can service the SCI without exiting wait 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.
