Receive Output Mute: Writing a “1” to this bit, mutes receive
outputs at RPOS/RDATA and RNEG/LCV pins to a “0” state for
any channel that detects an RLOS condition.
N
Extended LOS: Writing a “1” to this bit extends the number of
zeros at the receive input of each channel before RLOS is
declared to 4096 bits. Writing a “0” reverts to the normal mode
(175+75 bits for T1 and 32 bits for E1).
In-Circuit-Testing: Writing a “1” to this bit configures all the
output pins of the chip in high impedance mode for In-Circuit-
Testing. Setting the ICT bit to “1” is equivalent to connecting
the Hardware ICT pin 88 to ground.
Wire Gauge Selector Bit 1:
This bit together with bit D6 are used to select wire gauge size
as shown in the table below.
Wire Gauge Selector Bit 0:
See bit D7.
In Host mode, setting this bit to “1” transfers the control of the
Transmit On/Off function to the TXON_n Hardware control
pins.
N
Termination Control.
In Host mode, setting this bit to “1” transfers the control of the
RXTSEL to the RXTSEL Hardware control pin.
