Bits 7:3 Reserved

Bits 2:0 PSC[2:0]: Prescaler value

The prescaler value divides the CK_PSC clock frequency.

The counter clock frequency fCK_CNT is equal to fCK_PSC / 2(PSC[2:0]). PSC[7:3] are forced to 0 by

hardware.

PSCR contains the value which will be loaded in the active prescaler register at each update event

(including when the counter is cleared through UG bit of TIMx_EGR register).

This means that an update event must be generated in order that a new prescaler value can be

taken into account.
