Note:
Starting both timers synchronously in response to an external trigger
This example, sets the enable of Timer 1 when its TI1 input rises, and the enable of Timer 2
with the enable of Timer 1. Refer to
aligned, Timer 1 must be configured in master/slave mode (slave with respect to TI1, master
with respect to Timer 2):

When a rising edge occurs on TI1 (Timer 1), both counters start counting synchronously on
the internal clock and both timers' INT_TIMTIF flags are set.
In this example both timers are initialized before starting by setting their respective TIM_UG
bits. Both counters starts from 0, but an offset can be inserted between them by writing any
of the counter registers (TIMx_CNT). The master/slave mode inserts a delay between
CNT_EN and CK_PSC on Timer 1.
Figure 50. Triggering Timers 1 and 2 with Timer 1 TI1 input
Configure Timer 1 in master mode to send its Enable as trigger output (TIM_MMS =
001 in the TIM1_CR2 register).
Configure Timer 1 slave mode to get the input trigger from TI1 (TIM_TS = 100 in the
TIM1_SMCR register).
Configure Timer 1 in trigger mode (TIM_SMS = 110 in the TIM1_SMCR register).
Configure the Timer 1 in master/slave mode by writing TIM_MSM = 1 (TIM1_SMCR
register).
Configure Timer 2 to get the input trigger from Timer 1 (TIM_TS = 000 in the
TIM2_SMCR register).
Configure Timer 2 in trigger mode (TIM_SMS = 110 in the TIM2_SMCR register).
