40.7.38 PWM Comparison x Mode Register
Name: PWM_CMPMx
Address: 0x40000138 [0], 0x40000148 [1], 0x40000158 [2], 0x40000168 [3], 0x40000178 [4], 0x40000188 [5],
0x40000198 [6], 0x400001A8 [7]
Access: Read/Write
 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: The field CPRCNT is read-only
 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.
Note: The field CUPRCNT is read-only
