CLKSEL2
Clock Select Inputs for Master Clock Synthesizer bit 2:
In Host mode, CLKSEL[2:0] are input signals to a programma-
ble frequency synthesizer that can be used to generate a mas-
ter clock from an external accurate clock source according to
the following table;
In Hardware mode, the state of these signals are ignored and
the master frequency PLL is controlled by the corresponding
Hardware pins.

D3
MCLKRATE
Master clock Rate Select: The state of this bit programs the
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”.
R/W
0
D2
RXMUTE
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.
NOTE: RCLK is not muted.
R/W
0
D1
EXLOS
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).
R/W
0
D0
ICT
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.
