D5
ARAOS_n
Automatic Receive All Ones
If ARAOS_n is selected, an all ones pattern will be sent to the
RPOS/RNEG outputs if the channel experiences an RLOS condi-
tion. If RLOS does not occur, ARAOS_n will remain inactive.
"0" = Disabled
"1" = Enabled

0
D4
ATAOS_n
Automatic Transmit All Ones
If ATAOS_n is selected, an all ones pattern will be transmitted from
TTIP/TRING if the channel experiences an RLOS condition. If
RLOS does not occur, ATAOS_n will remain inactive.
"0" = Disabled
"1" = Enabled
R/W
0
D3
TAOS_n
Transmit All Ones
If TAOS_n is selected, an all ones pattern will be transmitted from
TTIP/TRING if the transmitter is turned on. Remote Loop Back
has priority over TAOS.
"0" = Disabled
"1" = Enabled
R/W
0
D2
TXOE_n
Transmit Output Enable
Upon power up, the tranmitters are tri-stated. This bit is used to
enable the transmitter for this channel if the TxOE pin is pulled
"High". If the TxOE pin is pulled "Low", all 8 transmitters are tri-
stated.
"0" = Transmitter is disabled
"1" = Transmitter is enabled if TxOE pin is pulled "High"

Receive Line Impedance Select
TERSEL[1:0] are used to select the internal line impedance.
"00" = 75
for Tx and "High-Z" for Rx
"01" = 120
for Tx and "High-Z" for Rx
