Read/Write

0: No effect
1: If the UPDM field is set to ‘0’ in 

, 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.
This bit is automatically reset when the update is done.
