AF: Assigned Frame. If a bit is set, the FLEX decoder will consider the corresponding frame to be
assigned via an addressâs home frame and pager collapse. (value after reset=0)
12.3.11 User Address Enable Packet
The User Address Enable Packet is used to enable and disable the 16 user address words.
Although the host is allowed to change the user address words while the FLEX decoder is
decoding FLEX signals, the host must disable a user address word before changing it. The ID of
the User Address Enable Packet is 120 (decimal).
