68.7.38 PWM Comparison x Value Update Register
This register acts as a double buffer for the CV and CVM values. This prevents an unexpected comparison x match.
Only the first 16 bits (channel counter size) of field CVUPD are significant.
CAUTION: The write of the register PWM_CMPVUPDx must be followed by a write of
the register PWM_CMPMUPDx.

Bit 24 – CVMUPD Comparison x Value Mode Update
Note: This bit is not relevant if the counter of the channel 0 is left-aligned (CALG = 0
in PWM
Channel Mode Register)
| Value | Description |
|---|---|
| 0 | The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is incrementing. |
| 1 | The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is decrementing. |
Bits 23:0 – CVUPD[23:0] Comparison x Value Update
Defines the comparison x value to be compared with the counter of the channel 0.
