USER ADDRESS ASSIGNMENT PACKETS
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).

The KS8701 has 16 user address words. Each word can be programmed to be a short address, part of a long

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.

the second word must be in the address index immediately following the first word.

is set, the TOA bit of the other word of the long address must also be set.
