<ENABLE INDEPENDENT CHANNEL CONTROL>
0 Common control – both channels use common control settings for test patterns, offset correction,
gain, gain correction and SNRBoost functions. These settings can be specified in a single set of
registers.
1 Independent control – both channels can be programmed with independent control settings for test
patterns, offset correction and SNRBoost functions. Separate registers are available for each
channel.
