The Watchdog Timer (WDT) of the N76E003 has a hardware limitation. As long as the pre-scale of system frequency is enabled, the WDT cannot wake up the chip.
Since the N76E003 supports the Wakeup Timer (WKT) function, it is recommended to use the WKT to wake up in Power-down mode and use the WDT to prevent the program from entering un-expectable status.
