Refer to the CC4P description above.
Refer to the CC4E description above.
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).
