Write-only

This register acts as a double buffer for the CEN, CTR, CPR and CUPR values. This prevents an unexpected comparison x 
match.

0 = The comparison x is disabled and can not match.

1 = The comparison x is enabled and can match.

The comparison x is performed when the value of the comparison x period counter (CPRCNT) reaches the value defined by CTR.

CPR defines the maximum value of the comparison x period counter (CPRCNT). The comparison x value is performed periodi-
cally once every CPR+1 periods of the channel 0 counter.

Defines the time between each update of the comparison x mode and the comparison x value. This time is equal to CUPR+1 peri-
ods of the channel 0 counter.
