Identification.
The identification register contains a unique revision code that is factory
programmed for each revision of the LXT384 Transceiver.
Revision code for the LXT384 Transceiver stepping A4 is 00h.
Revision code for the LXT384 Transceiver stepping A5 is 15h.

7:0
AL7:0
Analog Loopback.
Setting one of the AL bits to ‘1’ enables analog loopback for its corresponding
transceiver.

Remote Loopback.
Setting one of the RL bits to ‘1’ enables remote loopback for its corresponding
transceiver.

Description
R/W
7:0
TAOS7:0
Transmit All Ones (Enable).
On power-up, the TAOS7:0 bits are cleared to ‘0’.
Setting one of the TAOS bits to ‘1’ causes a continuous stream of marks
(that is, ones) to be sent out to the TTIP pin and TRING pin of the
corresponding transmitter.
There are two possible timing references for these bits, depending on the
availability of MCLK. If MCLK:
Is not available, then the channel TCLK is used as the timing reference
for the output.
Is available, MCLK is used as the timing reference for the output.
NOTE: TAOS is not available in data-recovery mode or the line-driver mode
(that is, when both MCLK = High and TCLK = High).
