The PWM output period is determined by the CCRAregister value together with the TM clock while
the PWM duty cycle is defined by the CCRP register value.

If f

The STM PWM output frequency=(f

SYS
/2048=7.8125kHz, duty=128/(2×256)=25%.
If the Duty value defined by the CCRAregister is equal to or greater than the Period value, then the
PWM output duty is 100%.

The PWM output period is determined by the CCRAregister value together with the TM clock while
the PWM duty cycle is defined by the (CCRP x 256) except when the CCRP value is equal to 0.
