Capture/compare channels
Each capture/compare channel is built around a capture/compare register including a
shadow register, an input stage for capture with digital filter, multiplexing and prescaler, and
an output stage with comparator and output control.

corresponding TIy input to generate a filtered signal (TIyF). Then an edge detector with
polarity selection generates a signal (TIyFPy) which can be used either as trigger input by
the slave mode controller or as the capture command. It is prescaled before the capture
register (ICyPS).
Figure 29. Capture/compare channel (example: channel 1 input stage)
The output stage generates an intermediate reference signal, OCyREF, which is only used
internally. OCyREF is always active high, but it may be inverted to create the output signal,
OCy, that controls a GPIO output.
