Decoder control address
The decoder control address (1E H) contains a
data ready flag (DR), a battery low flag (BL),
an out of range flag (OR), a battery fail flag
(BF), a decoder standby flag (STB), a call
termination indication flag (CT), a decoder
software reset (RES), and a decoder on/off
control bit (ON). It not only records the status
information but controls the operation of the
decoder.
Any data written to the decoder control ad-
dress cannot change the OR, BF, STB and CT
flags.
If the status of the battery fail (BF) changes
from “1” to “0”, the following conditions occur.
The pager controller generates an interrupt if
the value of the data ready interrupt flag is “1”.
The pager controller does not generate an
interrupt and no data is transmitted if the
value of the data ready interrupt flag is “0”.
On the other hand, if the status of the battery
fail (BF) changes from “0” to “1”, the internal
node PA.7 of the pager controller will supply a
wake-up function.
After the decoder asserts the data transfer
request, the data ready interrupt is generated
and the DR bit (bit 7 of 1E H) is cleared low;
then the data ready interrupt subroutine runs
to process the call data and resets the DR bit
high.
