BITS
columns 8/9/A/C mapped to DRCS when DRCS characters enabled, allowing
64 DRCS characters (logic 1), default (logic 0) only columns 8/9 mapped to
DRCS when DRCS characters enabled, allowing 32 DRCS characters
display black background as video on Page B (logic 1)
enable meshing of coloured background on Page B (logic 1)
enable meshing of black background on Page B (logic 1)
disable display of shadow/fringing on Page B (logic 0) display shadow/ fringe
(default SE black) on Page B (logic 1)
enable display of Teletext boxes in memory row 24 of Page B (logic 1)
enable display of Teletext boxes in memory row 1 to 23 of Page B (logic 1)
enable display of Teletext boxes in memory row 0 of Page B (logic 1)
Defines colour to be displayed instead of TV picture and black background for
Page B; these bits are equivalent to the RGB components. SCRB<2:0>:
conventional internal memory storage of acquisition data (logic 0) enables
multi-page acquisition operation for software controlled storage of acquired data
in external SRAM (logic 1)
display Page B configured for CC mode (logic 1)
display Page B active during two page mode (logic 1)
select upper bank for display Page B (logic 1)
current display page for Page B
disable twist function for Page B (logic 0) enable twist character set for Page B
(logic 1)
twist character set selection for Page B
character code columns 8 and 9 defined as single plane characters for display
Page B (logic 0) character code columns 8 and 9 defined as double plane
characters (special graphics characters) for display Page B (logic 1)
enable use of OSD LAN B<2:0> to define language option for display, instead of
C12, C13 and C14 for display Page B
alternative C12, C13 and C14 bits for use with OSD menus for display Page B
