• WKMODE0: Wake-up Mode 0
• CPTWK0: Counter on Wake-up 0
Defines the number of 16 Slow Clock cycles, the level detection on the corresponding input pin shall last before the wake-
up event occurs. Because of the internal synchronization of WKUP0, the
(CPTWK x 16 + 1) Slow Clock cycles after the event on WKUP.
