Duplicate call suppression
The HT9480 provides a Duplicate Call Suppres-
sion with time-out facility, to identify duplicate
call reception. In display pager mode, duplicate
call indication is achieved only via the
μ
C inter-
face. A call is assumed to be duplicate if its
address and function bit setting is equal to the
latest received call, which initialized the call
address and function bit reference. The Dupli-
cate Call suppression time-out is selected by
programming SPF06, SPF07.
Configuration RAM organization
The decoder contains a 21-byte RAM to store 6
user addresses, 6 independently programmable
frame numbers and specially programmed
function bits (SPF00~SPF23) for the decoder
application configuration. The data memory is
mapped to the addresses 40H~54H of bank 27.
