Register 0x014: Master Line Loop Back
This register controls line loop back for the three serial data links.
LLBEN[0,4,8]
The line loopback enable bits (LLBEN[0,4,8]) control line loopback for links #0, 4 and 8.
When LLBEN[n] is set high, the data on RD[n] is passed verbatim to TD[n], which is then
updated on the falling edge of RCLK[n]. TCLK[n] is ignored. When LLBEN[n] is set low,
TD[n] is processed normally.
