If the Duty value defined by the CCRA register is equal to or greater than the Period value, then the
PWM output duty is 100%.

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

The STM PWM output frequency=(f
If the Duty value defined by the CCRA register is equal to or greater than the Period value, then the
PWM output duty is 100%.
16-bit STM, PWM Mode, Edge-aligned Mode, TnDPX=1
The PWM output period is determined by the CCRA register value together with the TM clock
while the PWM duty cycle is defined by the (CCRP×256) except when the CCRP value is equal to
000b.
