Note: The gated mode must not be used if tim_ti1f_ed is selected as the trigger input (TS=00100). Indeed, tim_ti1f_ed outputs 1 pulse for each transition on tim_ti1f, whereas the gated mode checks the level of the trigger signal. Note: The clock of the slave peripherals (timer, ADC, ...) receiving the tim_trgo signal must be enabled prior to receive events from the master timer, and the clock frequency (prescaler) must not be changed on-the-fly while triggers are received from the master timer. 16 1 read-write 0 1 TS2 Trigger selection This bit-field selects the trigger input to be used to synchronize the counter. Others: Reserved See for product specific implementation details.

Indeed, tim_ti1f_ed outputs 1 pulse for each transition on tim_ti1f, whereas the gated mode checks the level of the trigger signal. Note: The clock of the slave peripherals (timer, ADC, ...) receiving the tim_trgo signal must be enabled prior to receive events from the master timer, and the clock frequency (prescaler) must not be changed on-the-fly while triggers are received from the master timer. 16 1 read-write TS2 Trigger selection This bit-field selects the trigger input to be used to synchronize the counter.
