These bits are the Receive Loop-back De-Activation Code
sequence.
Receive Loop-back De-Activation Code Enable:
When this bit is set to 0:
Receive Loop-back De-Activation Code is disabled. Receive
Loop-back De-Activation Code is not sent to the line.
When this bit is set to 1:
Receive Loop-back De-Activation Code is enabled. Receive
Loop-back De-Activation Code is generated and repeatedly sent
to the line instead of payload data.
Transmit Sa8 Select:
This bit determines whether the source of Sa8 bit is from trans-
mit serial input or transmit Sa8 register.
When this bit is set to 0:
The source of .Sa8 bit is from transmit serial input.
When this bit is set to 1:
The source of .Sa8 bit is from transmit Sa8 register.
