CH[5:0] : HEIGHT of the character strips in scan lines. For
each scan line, the number of the slice which is
displayed is given by :

: ON/OFF (if 0, R, G, B and FBLK outputs are 0).
: Fast blanking control :
= 1, forces FBLK pin at "1" outside and inside the
OSD area. This leads to blank video RGB and
to only display OSD RGB.
= 0, FBLK pin is driven according character code
for normal display of OSD data.
FL[1:0] : Flashing mode :
-
00 : No flashing.
The character attribute is ignored,
