XGA dual input flat panel controller
SAA6713H
Toalloweasyaccess to thewindow definition whenwriting
data to the OSD text, the cursor will perform an
auto-increment function to the next right element (or to a
new line, if the line ends) each time an element is written
to the RAM which is allowing an I
2
C-bus burst
transmission to define the window contents. The actual
cursor values can be read back at any time.
Each element of the OSD text window consist of 23 bits.
They represent the property of an OSD text character. The
elements are accessible via the OSDT_PROP2,
OSDT_PROP1 and OSDT_PROP0 registers
(see Table 39). All information encoded with these
OSDT_PROP registers is valid for one character only, so
the look of an OSD text can be changed mainly on a
character base. The colour definition elements
bg_colour[2:0] and fg_colour[2:0]/palette[2:0] are not
definingacolourdirectlybutareassigningavaluefromthe
global OSD colour tables which are defined within register
page 9. For single colour characters, the user can select
one of the eight possible foreground colours and one of
eight possible background colours. For multicolour
characters one out of eight possible colour palettes is
chosen; each defining four colours (1 background and
3 foreground) to be used within this character. The
information whether a character is a multicolour character
or a single colour character is derived from the charcode
and the value of sc_startcode (OSDT_SC_HI and
OSDT_SC_LO) that defines the multi or single character
mapping inside the font RAM.

DESCRIPTION
blink[1:0]
defines the blink mode of the character
00: blinking is off
01: blinking of foreground only
10: character is inverse, no blinking
11: blinking by inversion of foreground and background colour
if set to logic 1, the character will be displayed with an 1 pixel horizontal and vertical shadow
if set to logic 1, the background colour is displayed transparent
if set to logic 1, the foreground colour is displayed transparent
if set to logic 1, the background will not be displayed solid but alpha-blended with picture data using
the global definable background alpha-blending factor (OSDT_BGA)
if set to logic 1, the foreground will not be displayed solid but alpha-blended with picture data using
the global definable foreground alpha-blending factor (OSDT_FGA)
defines which of the 8 definable text background colours is used for this character
shared programming bits; fg_colour defines which of the 8 text foreground colours is used for this
character (only valid if charcode points to a single colour character) and palette defines used
multicolour palette (only valid if charcode points to a multicolour character)
if set to logic 1, the character is selected from ROM; if set to logic 0, then the character is selected
from RAM
indicates the desired character inside the font ROM/GEN or the font RAM
