Transmit Loopback Code
These seven bits determine the transmit loopback code. The MSB
of the transmit loopback code is loaded first for transmission.
0
TXLBCENB
R/W
0
Transmit Loopback Code Enable
This bit enables loopback code generation in the transmit path.
Transmit loopback code is generated by writing the transmit loop-
back code in this register and enabling it using this bit. The length
and the format of the transmit loopback code is determined by the
Loopback Code Control Register (Register address: 0xn124)
0 = Disables the transmit loopback code generation.
1 = Enables the transmit loopback code generation.

Receive activation loopback code
These seven bits determine the receive loopback activation code.
The MSB of the receive activation loopback code is received first.

RXLBACENB
R/W
0
Receive activation loopback code enable
This bit enables the receive loopback activation code detection.
Receive loopback activation code is detected by writing the
expected receive activation loopback code in this register and
enabling it using this bit.
The length and format of the Receive loopback activation code is
determined by the Loopback Code Control Register (Register
0xn124).
0 = Disables the receive loopback code activation detection.
1 = Enables the receive loopback code activation detection.

enabling it using this bit.
The length and format of the Receive loopback deactivation code is
determined by the Loopback Code Control Register (Register
0xn124).
0 = Disables the receive loopback code deactivation detection.
1 = Enables the receive loopback code deactivation detection.
