MMS2

Bits 20-23: Master mode selection 2.

Allowed values:
0: Reset: Reset - the UG bit from the TIMx_EGR register is used as trigger output (TRGO2). If the reset is generated by the trigger input (slave mode controller configured in reset mode), the signal on TRGO2 is delayed compared to the actual reset
1: Enable: Enable - the Counter Enable signal CNT_EN is used as trigger output (TRGO2). It is useful to start several timers at the same time or to control a window in which a slave timer is enabled. The Counter Enable signal is generated by a logic AND between the CEN control bit and the trigger input when configured in Gated mode. When the Counter Enable signal is controlled by the trigger input, there is a delay on TRGO2, except if the Master/Slave mode is selected (see the MSM bit description in TIMx_SMCR register)
2: Update: Update - the update event is selected as trigger output (TRGO2). For instance, a master timer can then be used as a prescaler for a slave timer
3: ComparePulse: Compare pulse - the trigger output sends a positive pulse when the CC1IF flag is to be set (even if it was already high), as soon as a capture or compare match occurs (TRGO2)
4: CompareOC1: Compare - OC1REFC signal is used as trigger output (TRGO2)
5: CompareOC2: Compare - OC2REFC signal is used as trigger output (TRGO2)
6: CompareOC3: Compare - OC3REFC signal is used as trigger output (TRGO2)
7: CompareOC4: Compare - OC4REFC signal is used as trigger output (TRGO2)
8: CompareOC5: Compare - OC5REFC signal is used as trigger output (TRGO2)
9: CompareOC6: Compare - OC6REFC signal is used as trigger output (TRGO2)
10: PulseOC4: Compare Pulse - OC4REFC rising or falling edges generate pulses on TRGO2
11: PulseOC6: Compare Pulse - OC6REFC rising or falling edges generate pulses on TRGO2
12: RisingOC4_6: Compare Pulse - OC4REFC or OC6REFC rising edges generate pulses on TRGO2
13: RisingOC4_FallingOC6: Compare Pulse - OC4REFC rising or OC6REFC falling edges generate pulses on TRGO2
14: RisingOC5_6: Compare Pulse - OC5REFC or OC6REFC rising edges generate pulses on TRGO2
15: RisingOC5_FallingOC6: Compare Pulse - OC5REFC rising or OC6REFC falling edges generate pulses on TRGO2

If SMS[3]=1 then Combined reset + trigger mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter, generates an update of the registers and starts the counter
1: EncoderMode1: Encoder mode 1 - Counter counts up/down on TI2FP1 edge depending on TI1FP2 level
2: EncoderMode2: Encoder mode 2 - Counter counts up/down on TI1FP2 edge depending on TI2FP1 level
3: EncoderMode3: Encoder mode 3 - Counter counts up/down on both TI1FP1 and TI2FP2 edges depending on the level of the other input
4: ResetMode: Reset Mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter and generates an update of the registers
5: GatedMode: Gated Mode - The counter clock is enabled when the trigger input (TRGI) is high. The counter stops (but is not reset) as soon as the trigger becomes low. Both start and stop of the counter are controlled
6: TriggerMode: Trigger Mode - The counter starts at a rising edge of the trigger TRGI (but it is not reset). Only the start of the counter is controlled
7: ExtClockMode: External Clock Mode 1 - Rising edges of the selected trigger (TRGI) clock the counter
