Host-to-Decoder Packet Descriptions

USER ADDRESS ASSIGNMENT PACKETS
The KS8701 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 KS8701 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 KS8701 when an
address is detected. See
“
Address Packet
”
on page 41 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 KS8701 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.
