• CEN: Comparison x Enable
0 = The comparison x is disabled and can not match.
1 = The comparison x is enabled and can match.
• CTR: Comparison x Trigger
The comparison x is performed when the value of the comparison x period counter (CPRCNT) reaches the value defined
by CTR.
• CPR: Comparison x Period
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.
• CPRCNT: Comparison x Period Counter
Reports the value of the comparison x period counter.
Note:
• CUPR: Comparison x Update Period
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.
• CUPRCNT: Comparison x Update Period Counter
Reports the value of the comparison x update period counter.
