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:

)

CAUTION: to be taken into account, the write of the register PWM_CMPVUPDx must be followed by a write of the register 
PWM_CMPMUPDx.
