| Value | Description |
|---|---|
| 0 | No effect |
| 1 | If the UPDM field is set to ‘0’ in PWM Sync Channels Mode Register, writing the UPDULOCK bit to ‘1’ triggers the update of the period value, the duty-cycle and the dead-time values of synchronous channels at the beginning of the next PWM period. If the field UPDM is set to ‘1’ or ‘2’, writing the UPDULOCK bit to ‘1’ triggers only the update of the period value and of the dead-time values of synchronous channels. |
