Every time the Burst Timer expires, the bursting slave must send a BACK to a different master. If more than one burst message are configured, then the same burst message (command) is burst to each master to complete a burst cycle. It is possible that a transaction will occur between the BACK messages. The burst slave must publish the burst message to each master by alternating master address on each BACK.
