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

OSD

:

ON/OFF (if 0, R, G, B and FBLK outputs are 0).

FBK

:

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,

P[9:6]

:

P[13:10] and P[5:0] = 0; up to 16 different pages can be stored in the RAM.
