MESSAGE PACKET
The Message Field follows the Vector Field in the FLEX protocol. It contains the message data, checksum
information, and may contain fragment numbers and message numbers. If the error bit of a vector word is not set
and the vector word indicates that there are message words associated with the page, the message words are
sent in Message Packets.
The ID of the Message Packet is the word number where the message word was received in the frame.

Word number of message word (3 - 87 decimal). Describes the location of the message word in the
frame.
Set if more than 2 bit errors are detected in the word.
Phase on which the message word was found (0=a, 1=b, 2=c, 3=d)
These are the information bits of the message word. The definitions of these bits depend on the
vector type and which word of the message is being received.
