TIM_PSC: Prescaler value
The prescaler divides the internal timer clock frequency. The counter clock frequency CK_CNT
is equal to fCK_PSC / (2 ^ TIM_PSC). Clock division factors can range from 1 through 32768.
The division factor is loaded into the shadow prescaler register at each update event (including
when the counter is cleared through TIM_UG bit of TMR1_EGR register or through the trigger
controller when configured in reset mode).
TIM_ARR: Auto-reload value
TIM_ARR is the value to be loaded in the shadow auto-reload register.
The auto-reload register is buffered. Writing or reading the auto-reload register accesses the
buffer register. The content of the buffer register is transfered in the shadow register
permanently or at each update event UEV, depending on the auto-reload buffer enable bit
(TIM_ARBE) in TMRx_CR1 register. The update event is sent when the counter reaches the
overflow point (or underflow point when down-counting) and if the TIM_UDIS bit equals 0 in the
TMRx_CR1 register. It can also be generated by software. The counter is blocked while the
auto-reload value is 0.
