Refer to the CC4P description above.
Refer to the CC43 description above.
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).
