Transmitter ON: Writing a "1" into this bit location turns on the
Transmit Section. A ‘0’ in this bit location, shuts off the transmit-
ter. In this mode the TTIP and TRING driver outputs will be tri-
stated for power reduction or redundancy applications.
Loop-Back control bit 2: This bit together with the LOOP1 and
LOOP0 bits control the Loop-Back modes of the chip according
to the following table:
Loop-Back control bit 1: See description of bit D2 for the func-
tion of this bit.
