PWM Channel Period Register
Register Name: PWM_CPRDx
Access Type:
Only the first 16 bits (internal channel counter size) are significative.
• CPRD: Channel Period
If the waveform is left-aligned, then the output waveform period depends on the counter source clock and can be
calculated:
If the waveform is center-aligned, then the output waveform period depends on the counter source clockand can be
calculated:

By using the Master Clock (MCK) divided by an X given prescaler value (with X being 1, 2, 4, 8, 16, 32, 64, 128,
256, 512, or 1024). The resulting period formula will be:
By using a Master Clock divided by one of both DIVA or DIVB divider, the formula becomes, respectively:
