User address format
A user address in the POCSAG code consists of
21 bits. Three of the 21 bits are coded in the
frame number and are therefore not explicitly
transmitted. In the decoder, the addresses A, B,
C, D, E and F can use 6 different frames respec-
tively. E very address has to be explicitly en-
abled by resetting the associated enable bit.
E xamples:
Address decimal value: RICA=10535
Binary equivalent(14 bits): 10100100100111
Binary equivalent(18+3 bits):
000000010100100100111

Configuration
The program mode changes to the STANDBY
state by setting the ON bit high at any time. The
configuration RAM can be programmed only
when the value of the STB flag is 1. After the
configuration RAM is programmed and the ON
bit is set low, the system quits the program
mode and resumes normal operation.
Test mode
The test mode of the decoder is selected by
setting the TS pin low at any time. In the test
mode, the RF control outputs BS1 and BS3 are
set high constantly, but BS2 is set low.
After the TS pin is set high the decoder exits the
test mode.
RF control
The HT9480 provides the BS1-BS3 signals for
RF control.
