Address Packet
The Address Field follows the Block Information Field in the FLEX protocol. See
Appendix A for additional information. It contains all of the addresses in the frame. If
less than three bit errors are detected in a received address word and it matches an
enabled address assigned to the FLEX chip IC, an Address Packet will be sent to the
host processor. The Address Packet contains assorted data about the address and its
associated vector and message. The ID of an Address Packet is 1 (decimal).
