The Phase Delay Control section of the datasheet says:
Note that the phase delay adjustment requires the use of the SYNC function pin.
however I see that there is also a sync_bar register bitwhich isn't mentioned except in the register map.
Given that the function pin has an internal pullup canI simply float it and use the register bit when configuringa phase delay between two outputs?
The sync_bar register bit has the same functionality as the SYNC function pin. Since the SYNC function pin already has internal pull-up resistors, this pin can be left floating when not in use.
