Token Packet: Packet to be issued from the host at the time of transaction start.
Data Packet: Packet to use at the time of data transfer.
SOF Packet: Packet to start the frame to be issued from the host for every 1ms.
Hand Shake Packet: Packet to use at the transaction which controls flow.
Note: In each packet, there are SOP as start of packet, and EOP as end of packet.
