Battery-low indication output. If the decoder encounters a battery-low
condition a battery-low output latch is set HIGH. The battery-low output
latch may be tested for a battery-low condition, whenever the interface
enable input (IE) is active (HIGH), otherwise the battery-low output is
made high-impedance. The battery-low output latch is reset only, by
switching the decoder to OFF status.
Out-of-range indication output. Whenever the decoder detects an
out-of-range condition an out-of-range output latch is set HIGH after expiry
of the programmed out-of-range hold-off time selected by means of
special programming (SPF06 and SPF07) of the EEPROM. The
out-of-range latch may be tested for an out-of-range condition, whenever
the interface enable input (IE) is active (HIGH), otherwise the out-of-range
output is made high-impedance. The out-of- range output is reset by
detection of a valid data transmission or by switching the decoder to OFF
status.
Serial interface data output. During normal decoder operation, accepted
calls and possibly subsequent message data are serially output via this pin
in conjunction with the data strobe output (DS). This pin is also used to
output the EEPROM contents upon special command, if the decoder is
programmed for display pager.
Serial interface data strobe output. Provides a clock signal for the received
call data and EEPROM data appearing at the data output (DO). Each time
this output is LOW the data at DO is valid. Additional start and stop
conditions allow easy identification of data sequence start and end.
Frequency reference output. When programmed for ‘display pager’ mode,
this output provides a clock reference with 16384 or 32768 Hz per
second, selected by SPF32. See Chapter 7.
