Before enabling a TIM channel register for input capture operation, make
sure that the PTEx/TCHx pin or PTFx/TCHx pin is stable for at least two
bus clocks.
TOVx — Toggle-On-Overflow Bit
When TOVx is set, a TIM counter overflow takes precedence over a
channel x output compare if both occur at the same time.
MSxB:MSxA
When channel x is an output compare channel, this read/write bit
controls the behavior of the channel x output when the TIM counter
overflows. When channel x is an input capture channel, TOVx has no
effect. Reset clears the TOVx bit.
1 = Channel x pin toggles on TIM counter overflow.
0 = Channel x pin does not toggle on TIM counter overflow.
