Access:
This register acts as a double buffer for the CEN, CTR, CPR and CUPR values. This prevents an unexpected comparison
x match.
• CENUPD: Comparison x Enable Update
0 = The comparison x is disabled and can not match.
1 = The comparison x is enabled and can match.
• CTRUPD: Comparison x Trigger Update
The comparison x is performed when the value of the comparison x period counter (CPRCNT) reaches the value defined
by CTR.
• CPRUPD: Comparison x Period Update
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.
• CUPRUPD: Comparison x Update Period Update
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.
