OC[5]FE

Bit 2: Output compare 5 fast enable.

OC[5]PE

Bit 3: Output compare 5 preload enable.

OC[5]M

Bits 4-6: Output compare 5 mode.

Allowed values:
0: Frozen: The comparison between the output compare register TIMx_CCRy and the counter TIMx_CNT has no effect on the outputs / OpmMode1: Retriggerable OPM mode 1 - In up-counting mode, the channel is active until a trigger event is detected (on TRGI signal). In down-counting mode, the channel is inactive
1: ActiveOnMatch: Set channel to active level on match. OCyREF signal is forced high when the counter matches the capture/compare register / OpmMode2: Inversely to OpmMode1
2: InactiveOnMatch: Set channel to inactive level on match. OCyREF signal is forced low when the counter matches the capture/compare register / Reserved
3: Toggle: OCyREF toggles when TIMx_CNT=TIMx_CCRy / Reserved
4: ForceInactive: OCyREF is forced low / CombinedPwmMode1: OCyREF has the same behavior as in PWM mode 1. OCyREFC is the logical OR between OC1REF and OC2REF
5: ForceActive: OCyREF is forced high / CombinedPwmMode2: OCyREF has the same behavior as in PWM mode 2. OCyREFC is the logical AND between OC1REF and OC2REF
6: PwmMode1: In upcounting, channel is active as long as TIMx_CNT<TIMx_CCRy else inactive. In downcounting, channel is inactive as long as TIMx_CNT>TIMx_CCRy else active / AsymmetricPwmMode1: OCyREF has the same behavior as in PWM mode 1. OCyREFC outputs OC1REF when the counter is counting up, OC2REF when it is counting down
7: PwmMode2: Inversely to PwmMode1 / AsymmetricPwmMode2: Inversely to AsymmetricPwmMode1
