Master Clock Synthesizer to generate the T1/J1 or E1 clock. The
Master Clock Synthesizer will generate the E1 clock when
MCLKRATE = “0”, and the T1/J1 clock when MCLKRATE = “1”.
Receive Output Mute: Writing a "1" to this bit, mutes receive
outputs at RPOS/RDATA and RNEG/LCV pins to a "0" state.
N
Extended LOS: Writing a "1" to this bit extends the number of
zeros at the receive input 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 out-
put pins of the chip in "High" impedance mode for In-Circuit-Test-
ing. Setting ICT bit to “1” is equivalent to connecting the
Hardware ICT pin to ground.
Wire Gauge Selector Bit 1
This bit along with bit D6 are used to select wire gauge size as
shown in the table below.
Wire Gauge Selector Bit 0
See bit D7.
Transmit On/Off function to the TXON Hardware control pin.
N
Termination Control:
In Host mode, setting this bit to “1” transfers the control of the
RXTSEL to the RXTSEL Hardware control pin.
