Implementations
Bits 0:2 - Slave mode selection When external signals are selected the active edge of the trigger signal (TRGI) is linked to the polarity selected on the external input (see Input Control register and Control Register description. Other codes: reserved. Note: The gated mode must not be used if TI1F_ED is selected as the trigger input (TS=â00100â). Indeed, TI1F_ED outputs 1 pulse for each transition on TI1F, whereas the gated mode checks the level of the trigger signal. Note: The clock of the slave peripherals (timer, ADC, …) receiving the TRGO or the TRGO2 signals 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.
Bits 4:6 - Trigger selection This bit field selects the trigger input to be used to synchronize the counter. Other: Reserved See for more details on ITRx meaning for each Timer. Note: These bits must be changed only when they are not used (e.g. when SMS=000) to avoid wrong edge detections at the transition.
Bit 16 - Slave mode selection When external signals are selected the active edge of the trigger signal (TRGI) is linked to the polarity selected on the external input (see Input Control register and Control Register description. Other codes: reserved. Note: The gated mode must not be used if TI1F_ED is selected as the trigger input (TS=â00100â). Indeed, TI1F_ED outputs 1 pulse for each transition on TI1F, whereas the gated mode checks the level of the trigger signal. Note: The clock of the slave peripherals (timer, ADC, …) receiving the TRGO or the TRGO2 signals 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.
Bits 20:21 - Trigger selection This bit field selects the trigger input to be used to synchronize the counter. Other: Reserved See for more details on ITRx meaning for each Timer. Note: These bits must be changed only when they are not used (e.g. when SMS=000) to avoid wrong edge detections at the transition.
