Methods and systems of synchronizing events using a plurality of sequencing controllers are provided. For each sequencing controller, a serial communication bus (SCB) is monitored for a first reference level. Upon identifying that the SCB is at the first reference level for a predetermined period, a bit sequence indicative of an event position is broadcast to be arbitrated on the SCB. The SCB is monitored for the arbitrated bit sequence. Upon determining that the arbitrated bit sequence corresponds to the bit sequence of the event position, an event corresponding to the event position is enabled.
