0: An update event is generated as soon as a counter overflow occurs, a software update is
generated, or a hardware reset is generated by the slave mode controller. Shadow registers are
then loaded with their buffer register values.
1: An update event is not generated and shadow registers keep their value (TIMx_ARR,
TIMx_PSC, TIMx_CCRy). The counter and the prescaler are reinitialized if the TIM_UG bit is
set or if a hardware reset is received from the slave mode controller.
0: Counter disabled.
1: Counter enabled.
Note: External clock, gated mode and encoder mode can work only if the TIM_CEN bit has
0: TI1M (input of the digital filter) is connected to TI1 input.
1: TI1M is connected to the TI_HALL inputs (XOR combination).
