If LIRC (low-speed internal RC oscillator) is selected by Window Watchdog Timer (WWDT) as the clock source, can CPU be woken up by (WWDT interrupts after entering Power-down mode?  Issue Date:2016-11-29

When the CPU enters Idle or Power-down mode, the WWDT will automatically stop counting. Accordingly, the WWDT does not support the wake-up function in Power-down mode.
