mode instead of gated mode (TIM_SMS = 110 in the TIM2_SMCR register).
Figure 48. Triggering Timer 2 with enable of Timer 1
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):

●
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).
