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 
periodically 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 periods of the channel 0 counter.
