Access:
This register acts as a double buffer for the CV and CVM values. This prevents an unexpected comparison x match.
Only the first
• CVUPD: Comparison x Value Update
Define the comparison x value to be compared with the counter of the channel 0.
• CVMUPD: Comparison x Value Mode Update
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.
Note:
CAUTION: to be taken into account, the write of the register PWM_CMPVUPDx must be followed by a write of the register
PWM_CMPMUPDx.
