(1)Transmit Broadcast – Broadcast message transmitted over bi-directional master channel
(2)Receive Broadcast – Broadcast message received by slave channel
(3)Transmit Acknowledged – Acknowledged message transmitted over bi-directional master channel
(4)Receive Acknowledged – Acknowledged message received by slave channel
(5)Transmit-only Broadcast – Broadcast message transmitted by tx-only master channel
