Access:
• UPDULOCK: Synchronous Channels Update Unlock
0 = No effect
1 = If the UPDM field is set to “0” in
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.
This bit is automatically reset when the update is done.
