68.7.40 PWM Comparison x Mode Update Register
This register acts as a double buffer for the CEN, CTR, CPR and CUPR values. This prevents an unexpected comparison x match.

Bits 19:16 – CUPRUPD[3:0] 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.
Bits 11:8 – CPRUPD[3:0] 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.
Bits 7:4 – CTRUPD[3:0] 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.
Bit 0 – CENUPD Comparison x Enable Update
| Value | Description |
|---|---|
| 0 | The comparison x is disabled and can not match. |
| 1 | The comparison x is enabled and can match. |
