38.7.33 PWM Comparison x Value Update Register
Name:
PWM_CMPVUPDx
Address:
0x40020134 [0], 0x40020144 [1], 0x40020154 [2], 0x40020164 [3], 0x40020174 [4], 0x40020184 [5],
0x40020194 [6], 0x400201A4 [7]
Access:
Write-only
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 CV
UPD
are significant.
• 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.
incrementing.
1 = The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is
decrementing.
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.
PWM_CMPMUPDx.
