Can the WDT controller wake up the CPU from Power-down mode?

Yes, the WDT controller supports the WDT wake-up function. The user has to set the WDT wake-up enable bit (WTWKE = 1).
After the WDT wake-up enable bit is set (WTWKE=1) and WDT counter overflow trigger WDT-timeout event flag is set (WTIF=1), the WDT controller will wake up the CPU form Power-down mode.
