function of this bit.
Transmitter ON: Writing a “1” into this bit location turns on the
Transmit and Receive Sections of channel n. Writing a “0”
shuts off the Transmit Section of channel n. In this mode,
TTIP_n and TRING_n 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
function of this bit.
Loop-Back control bit 0: See description of bit D2 for the
function of this bit.
