PWM Comparison Units
The PWM provides 8 independent comparison units able to compare a programmed value with
the current value of the channel 0 counter (which is the channel counter of all synchronous
channels,
erate pulses on the event lines (used to synchronize ADC, see
Lines”), to generate software interrupts and to trigger PDC transfer requests for the synchronous
channels (see

bit is useless).
If a fault is active on the channel 0, the comparison is disabled and cannot match (see
36.6.2.6 “Fault
The user can define the periodicity of the comparison x by the fields CTR and CPR (in
PWM_CMPxV). The comparison is performed periodically once every CPR+1 periods of the
counter of the channel 0, when the value of the comparison period counter CPRCNT (in
PWM_CMPxM) reaches the value defined by CTR. CPR is the maximum value of the compari-
son period counter CPRCNT. If CPR=CTR=0, the comparison is performed at each period of the
counter of the channel 0.
The comparison x configuration can be modified while the channel 0 is enabled by using the
