The PWRON signal is debounced 1024*CLK32K (maximum 1026*CLK32K) falling edge in master mode.
Figure 13-1 is a sample debouncing sequence chronogram.
Figure 13-1. Debouncing Sequence Chronogram Example
Event1 is correctly debounced after 5 ms. Event2 is debounced after 50ms + dT because the capture of
the event is considered after the next rising edge of the 50-ms clock.
