Advanced-control timer (TIM1) RM0453
808/1450 RM0453 Rev 5
Bits 23:20 BK2F[3:0]: Break 2 filter
This bit-field defines the frequency used to sample BRK2 input and the length of the digital
filter applied to BRK2. The digital filter is made of an event counter in which N consecutive
events are needed to validate a transition on the output:
