7-0
TAOS7-TAOS0
Setting a bit to
1
causes a continuous stream of marks to be sent out at the TTIP and
TRING pins of the respective transceiver 7-0.
1. On power up all register bits are set to
0
.
2. MCLK is used as timing reference. If MCLK is not available then the channel TCLK is used as the
reference.This feature is not available in data recovery and line driver mode (MCLK= High and TCLK =
High).
