Returning Configuration Data
When the RETURN SETTING command is received before receiving the START TRANSMIT command,
the RETURN SETTING packet is broadcasted upon receiving the next own token. Items configured using
the INITIAL SETTING packet are transmitted as the RETURN SETTING packet.
After receiving the START TRANSMIT command, any RETURN SETTING command is ignored. For detail
information on each command, see the section of 2.4 COMMAND packets.
