for the STM32F7 reads on pg.1017:
OC1M: Output compare 1 mode
1000: Retriggerable OPM mode 1 - In up-counting mode, the channel is active until a trigger
event is detected (on TRGI signal). Then, a comparison is performed as in PWM mode 1
and the channels becomes inactive again at the next update. In down-counting mode, the
channel is inactive until a trigger event is detected (on TRGI signal). Then, a comparison is
performed as in PWM mode 1 and the channels becomes inactive again at the next update.
1001: Retriggerable OPM mode 2 - In up-counting mode, the channel is inactive until a
trigger event is detected (on TRGI signal). Then, a comparison is performed as in PWM
mode 2 and the channels becomes inactive again at the next update. In down-counting
mode, the channel is active until a trigger event is detected (on TRGI signal). Then, a
comparison is performed as in PWM mode 1 and the channels becomes active again at the
next update.
I highlighted the text in bold that might be a typo. Shouldn't the channel be inactive until a trigger event is detected? Otherwise, the following sentence where it says '...the channel is inactive again until a trigger event is detected' makes no sense.
