These registers contain the inband loopback code pattern to be transmitted. The

code is transmitted most significant bit ( IBC7) first, followed by IBC6 and so on.

The code, regardless of the length, must be aligned with the MSB always in the

IBC7 position (e.g., a 5-bit code would occupy the IBC7 through IBC2 bit

positions). To transmit a 3-bit or a 4-bit code pattern, the pattern must be paired

to form a double-sized code (i.e., the 3-bit code '011' would be written as the 6-

bit code '011011').
