• the waveform period. This channel parameter is defined in the CPRD field of the CPRDx
• the waveform duty cycle. This channel parameter is defined in the CDTY field of the CDTYx
• the waveform polarity. At the beginning of the period, the signal can be at high or low level.
• the waveform alignment. The output waveform can be left or center aligned. Center aligned
register.
- If the waveform is left aligned, then the output waveform period depends on the counter
source clock and can be calculated:
By using the Master Clock (CLK_PWM) 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:
If the waveform is center aligned then the output waveform period depends on the counter
source clock and can be calculated:
By using the Master Clock (CLK_PWM) 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

register.
If the waveform is left aligned then:
If the waveform is center aligned, then:
This property is defined in the CPOL field of the CMRx register. By default the signal starts by
a low level.
waveforms can be used to generate non overlapped waveforms. This property is defined in
the CALG field of the CMRx register. The default mode is left aligned.
