In Monochrome mode, SetReg3 bits 7:6 determine which input is to be sampled.
For Colour Line-by-Line, set control bit LINEBYLINE. For input selection, refer to Table 4, Colour Selection

MAX
The 3 input channels
are sampled in
parallel. The signal is
then gain and offset
adjusted before being
multiplexed into a
single data stream
and converted by the
ADC, giving an output
data rate of 6MSPS
max.
As mode 1 except:
Only one input
channel at a time
is continuously
sampled.
