The bit positions CL[1:0] (bits 1 & 0) of this register indicate the length of the
inband loopback code sequence, as follows:
CL1
CL0

Code Length

Codes of 3 or 4 bits in length may be accommodated by treating them as half of
a double-sized code (i.e. a 3-bit code would use the 6-bit code length setting).
