General-purpose timers
110/209
When an update event 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:

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).
