Address Packet
The Address Field follows the Block Information Field in the FLEX protocol. 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 decoder, 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).

PA: Priority Address. Set if the address was received as a priority address.
p: Phase on which the address was detected (0=a, 1=b, 2=c, 3=d)
LA: Long Address type. Set if the address was programmed in the FLEX decoder as a long
address.
AI: Address Index (valid values are 0 through 15 and 128 through 159). The index identifies
which of the addresses was detected. Values 0 through 15 correspond to the 16 programmable
