The update of the comparison x configuration and the comparison x value is triggered periodi-
cally after the comparison x update period. It is defined by the field CUPR in the PWM_CMPxM.
The comparison unit has an update period counter independent from the period counter to trig-
ger this update. When the value of the comparison update period counter CUPRCNT (in
PWM_CMPxM) reaches the value defined by CUPR, the update is triggered. The comparison x
update period CUPR itself can be updated while the channel 0 is enabled by using the
PWM_CMPxMUPD register.
CAUTION: to be taken into account, the write of the register PWM_CMPxVUPD must be fol-
lowed by a write of the register PWM_CMPxMUPD.
The comparison match and the comparison update can be source of an interrupt, but only if it is
enabled and not masked. These interrupts can be enabled by the
ter 2”
