30.3.17 Bidirectional break inputs
Beside regular digital break inputs and internal break events coming from the comparators,
the timer 1 and 8 are featuring bidirectional break inputs/outputs combining the two sources,
as represented on Figure 259.
The TIMx_BKINy_COMPz pins are combining the COMPz output (to be configured in open
drain) and the Timerx’s TIMx_BKINy input. They allow to have:
- A global break information available for external MCUs or gate drivers shut down inputs,
with a single-pin.
- An internal comparator and multiple external open drain comparators outputs ORed
together and triggering a break event, when the multiple internal and external break inputs
must be merged.
