DD[7:0]
: _{HORIZONTAL DISPLAY DELAY from the HSYNC reference edge to the 1}^st _{pixel position of the charac-}
ter strips.
Unit = 6 pixel periods. Minimum value is 08H. First pixel position = [DD[7:0] - 6] x 6 + 54 with
DD[7:0] = 0,2,4,6 delay is 54 pixel and with DD[7:0] = 1,3,5 delay is 60 pixel

: 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.
: Flashing mode :
- 00: No flashing. The character attribute is ignored,
- 01: Flashing at f_F (50% duty cycle),
- 10: Flashing at 2 f_F
- 11: Flashing at 4 f_F
Note: f_F is 128 time vertical frequency.
: _{Address of the 1}^st _{descriptor of the current displayed pages.}
P[13:10] and P[5:0] = 0; up to 16 different pages can be stored in the RAM.
