but without setting the INT_TIMUIF flag. Thus no interrupt request is sent. This avoids generating both update
and capture interrupts when clearing the counter on the capture event.
When a UEV occurs, the update flag (the INT_TIMUIF bit in the INT_TIMxFLAG register) is set (unless TIM_USR
is 1) and the following registers are updated:
Figure 9-3, Figure 9-4, Figure 9-5, and Figure 9-6 show some examples of the counter behavior for different
clock frequencies when TIMx_ARR = 0x36.
The buffer of the prescaler is reloaded with the buffer value (contents of the TIMx_PSC register).
The auto-reload shadow register is updated with the buffer value (TIMx_ARR).
