Write-only

This register acts as a double buffer for the CV and CVM values. This prevents an unexpected comparison x match.

Only the first 16 bits (channel counter size) of field CV

UPD

 are significant.



Define the comparison x value to be compared with the counter of the channel 0.



0: The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is 
incrementing.

1: The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is 
decrementing.

Note: This bit is not relevant if the counter of the channel 0 is left-aligned (CALG = 0 in 

)

CAUTION: The write of the register PWM_CMPVUPDx must be followed by a write of the register PWM_CMPMUPDx.
