    Due to the PMU design, the PMU may not clear the WAKEUP bit after
    wakeup, therefore, the state machine at the power mode may enter
    the infinite loop during WFI.
    
    There is a solution that we can use the M0 to monitor the WAKEUP
    bit and clear it during power mode, then the state machine will be
    recovered immediately. Then, the DUT can exit the WFI normally.
