When the Transmit Drive Monitor circuitry in a given
line is connected to the line as illustrated in Figure 30,
then it monitors the line for transitions. As long as the
Transmit Drive Monitor circuitry detects transitions on
the line via the MTIP_(n) and MRing_(n) pins, it
keeps the DMO (Drive Monitor Output) signal "Low".
However, if the Transmit Drive Monitor circuit detects
no transitions on the line for 128+32 TxClk periods,
the DMO (Drive Monitor Output) signal toggles
"High".
N
OTE
:
The Transmit Drive Monitor circuit does not have to
be used to operate the Transmit Section of the XRT73L02.
This is purely a diagnostic feature.

EATURE
The XRT73L02 can command any channel to trans-
mit an all “1’s” pattern onto the line by toggling a sin-
gle input pin or by setting a single bit-field in one of
the Command Registers to "1".
N
OTE
:
When this feature is activated, the Transmit Section
of the configured channel in the XRT73L02 overwrites the
Terminal Equipment data with an all “1’s” pattern.
a. Operating in the Hardware Mode
Configure Channel (n) to transmit an all “1’s” pattern
by toggling the TAOS_(n) input pin “High". Terminate
the all “1’s” pattern by toggling the TAOS_(n) input pin
"Low".
b. Operating in the HOST Mode
Configure Channel (n) to transmit an all “1’s” pattern
by writing to Command Register CR1-(n) and setting
the TAOS_(n) bit-field (D3) to "1".
COMMAND REGISTER CR1-(N)
Terminate the all “1’s” pattern by writing to Command
Register CR1-(n) and setting the TAOS_(n) bit-field
(D3) to "0".

THE MICROPROCESSOR SERIAL INTER-
FACE
The on-chip Command Registers of XRT73L02 DS3/
E3/STS-1 Line Interface Unit IC are used to configure
the XRT73L02 into a wide-variety of modes. This
section discusses the following:
1. The description of the Command Registers.
2. A description on how to use the Microprocessor
Serial Interface.
