7.16.5.1
These CSGs are two CSGs with one output (see Fig.31).
They are splitted in CSGXa and CSGXb. The a and b part
are equal and the programming is as two separated CSGs.
So one can generate signals with four events each
line/frame.
7.16.6
The output interface includes a simple frame generator.
It may be useful when the front-end receives no signal, so
no front-end clock is available. The generated frame has
the same dimensions as the picture area. The frame colour
is programmable (OI_FCx). The on screen display is still
working. The generator may be switched on via the
OI_FC_EN register.

7.16.5.2
Normal CSGs with two action points. Additionally, CSG2
plus CSG3 can cooperate like CSG0/1 a/b on the output
CSG3.
7.16.5.3
No special or additional features. Two action points.
7.16.7
The output interface has four global modes, which can be
programmed with bits OI_enable, power_down and
blank_mode (register OI_CTRL0) according to Table 54.
The blank colour is programmable via
bits blank_colour_red, blank_colour_green
and blank_colour_blue.
