is triggered. The comparison x update period CUPR itself can be updated while the channel 0 is enabled by using
the PWM_CMPMUPDx register.
the PWM_CMPMUPDx register.
CAUTION: The write of PWM_CMPVUPDx must be followed by a write of PWM_CMPMUPDx.
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

The PWM provides 2 independent event lines intended to trigger actions in other peripherals (i.e. for the Analog-to-
Digital Converter (ADC )).

A pulse (one cycle of the peripheral clock) is generated on an event line, when at least one of the selected
comparisons is matching. The comparisons can be selected or unselected independently by the CSEL bits in the
