Transmit Loop-back Code Enable:
When this bit is set to 0:
Transmit Loop-back Code is disabled. Transmit Loop-back Code
is not sent to the line.
When this bit is set to 1:
Transmit Loop-back Code is enabled. Transmit Loop-back Code
is generated and repeatedly sent to the line instead of payload
data.
Receive Loop-back Activation Code Bit[6:0]:
These bits are the Receive Loop-back Activation Code
sequence.
Receive Loop-back Activation Code Enable:
When this bit is set to 0:
Receive Loop-back Activation Code is disabled. Receive Loop-
back Activation Code is not sent to the line.
When this bit is set to 1:
Receive Loop-back Activation Code is enabled. Receive Loop-
back Activation Code is generated and repeatedly sent to the
line instead of payload data.
