The same Bayer pattern can also be interlaced, and the interlaced
mode should be used with this type of CCD (see Figure 17b).
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 18b.

A third type of readout uses the Bayer pattern divided into three
different readout fields. The three-field mode should be used
with this type of CCD (see Figure 17c). 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 18c.
