Hi Lincheng,
When a wake-up event is detected, the device starts the main state machine again by detecting the VPRE configuration (buck or buck-boost), the wake-up source is reported to the dedicated SPI register and the fail-safe state machine is also restarted.
Fail safe registers configuration will lost to default value after wake-up from Sleep mode. Main registers configuration will not lost after wake-up from Sleep mode.
BRs, Tomas
