12.3.12
The FLEX decoder has 16 user address words. Each word can be programmed to be a short
address, part of a long address, or the first part of a network ID . The addresses are configured
using the Address Assignment Packets. Each user address can be configured as long or short and
tone-only or regular (network ID’s are short and regular). Although the host is allowed to send
these packets while the FLEX decoder is on, the host must disable the user address word by
clearing the corresponding UAE bit in the User Address Enable Packet before changing any of the
bits in the corresponding User Address Assignment Packet. This method allows for easy
reprogramming of user addresses without disrupting normal operation. The IDs for these packets
range from 128 to 143 (decimal).

a: User Address Word Number. This specifies which address word is being configured. A zero in
this field corresponds to address index zero (AI = 0) in the Address Packet received from the
FLEX decoder when an address is detected. See 12.4.2, Address Packet for a description of the
address index field.
LA: Long address. When this bit is set, the address is considered a long address. Both words of a
long address must have this bit set. The first word of a long address must have an even address
index and the second word must be in the address index immediately following the first word.
TOA: Tone-Only Address. When this bit is set, the FLEX decoder will consider this address a
tone-only address and will not decode a vector word when the address is received. If the TOA bit
of a long address word is set, the TOA bit of the other word of the long address must also be set.
A: Address word. This is the 21 bit value of the address word. Valid FLEX messaging addresses
or Network ID’s may be used.
