Bits 15:0 PSC[15:0]: Prescaler value
The counter clock frequency CK_CNT is equal to f
CK_PSC
/ (PSC[15:0] + 1).
PSC contains the value to be loaded in the active prescaler register at each update event
(including when the counter is cleared through UG bit of TIMx_EGR register or through
trigger controller when configured in “reset mode”).
