Single Rail mode
This bit must set to "1" for Single Rail mode to use LIU diagnotic fea-
tures. The Framer section must be programmed as well in Register
0x0101.
0 - Dual Rail
1 - Single Rail

Automatic Transmit All Ones Upon RLOS:
This bit enables automatic transmission of All Ones Pattern upon
detecting the Receive Loss of Signal (RLOS) condition.
Once this bit is enabled, the Transmit T1 Framer Block will automat-
ically transmit an All “Ones” data to the line for the channel that
detects an RLOS condition.
0 = Disables the “Automatic Transmit All Ones” feature upon detect-
ing RLOS
1 = Enables the “Automatic Transmit All Ones” feature upon detect-
ing RLOS

RCLKE
R/W
0
Receive Clock Data (Framer Bypass mode)
0 = RPOS/RNEG data is updated on the rising edge of RCLK
1 = RPOS/RNEG data is updated on the falling edge of RCLK
4
TCLKE
R/W
0
Transmit Clock Data (Framer Bypass mode)
0 = TPOS/TNEG data is sampled on the falling edge of TCLK
1 = TPOS/TNEG data is sampled on the rising edge of TCLK

R/W
0
Data Polarity
0 = Transmit input and receive output data is active “High”
1 = Transmit input and receive output data is active “Low”
