Master-slave management
The TIMERx can be synchronized with a trigger in several modes including the restart mode,
the pause mode and the event mode which is selected by the SMC [2:0] in the
TIMERx_SMCFG register. The trigger input of these modes can be selected by the TRGS
[2:0] in the TIMERx_SMCFG register.

If you choose the CI0FE0
or CI1FE1, configure the
CHxP and CHxNP for the
polarity selection and
inversion.
If you choose the ETIF,
For the ITIx no filter and
prescaler can be used.
For the CIx, configure Filter
by CHxCAPFLT, no
prescaler can be used.
