Setting a bit to “1” enables digital loopback for the respective transceiver. During digital
loopback LOS and TAOS stay active and independent of TCLK, while data received on
TPOS/TNEG/TCLK is looped back to RPOS/RNEG/RCLK. On power up all register
bits are set to “0.”
Setting a bit to “1” selects the ETSI 300233 LOS mode for the respective transceiver.
On power-on reset the register is set to “0” and G.775 LOS operation is selected.
Setting a bit to “1” enables automatic TAOS generation whenever a LOS condition is
detected in the respective transceiver. On power-on reset the register is set to “0.”
