The same Bayer pattern can also be interlaced, and the
interlaced mode should be used with this type of CCD (see
Figure 31). The color steering performs the proper multiplexing
of the R, G, and B gain values (loaded into the PxGA gain
registers) and is synchronized by the user with vertical (VD)
and horizontal (HD) sync pulses. For timing information,
see Figure 34.

A third type of readout uses the Bayer pattern divided into three
different readout fields. The 3-field mode should be used with
this type of CCD (see Figure 32). The color steering performs
the proper multiplexing of the R, G, and B gain values (loaded
into the PxGA gain registers) and is synchronized by the user
with vertical (VD) and horizontal (HD) sync pulses. For timing
information, see Figure 35.
