ON-SCREEN DISPLAY(OSD)
The ST639x OSD macrocell is a CMOSLSI char-
acter generatorwhich enable display ofcharacters
and symbols on the TV screen. The character
rounding function enhancesthe readability of the
characters. The ST639x OSD receives horizontal
and vertical synchronization signal and outputs
screen information via R, G, B and blanking pins.
The main characteristics of the macrocellare listed
below:
-
Number of display characters: 5 lines by 15
columns.
-
Number of character types: 128 characters in
two banks of 64 characters.
Only one bank
per screencan be used.
-
Character size: Four character heights (18H,
36H 54H, 72H), two heights are available per
screen,programmable byline.
-
Character format: 6x9 dots with character
roundingfunction.
-
Character colour: Eight colours available pro-
grammable byword.
-
Display position: 64 horizontal positions by
2/f
osc
and63 vertical positionsby 4 H
-
Word spacing: 64 positions programmable
from 2/f
osc
to128/f
osc
.
-
Line spacing:63 positionsprogrammablefrom
4 to 252 H.
-
Background: No background, square back-
groundor fringe background programmableby
word.
-
Background colour: Two of eight colours avail-
able programmableby word.
-
Display output: Three character data output
terminals (R,G,B) and ablank outputterminal.
-
Display on/off: Display data may be pro-
grammed on or off by word or entire screen.
The entire screen may be blanked.
FormatSpecification
The entire display can be turnedon or off through
the use of the global enable bit orthe display may
be selectively turned on or off by word. To turn off
the entiredisplay,theglobalenable bit(GE) should
be zero. If the global enable is one, the display is
controlledbythewordenable bits(WE).Theglobal
enable bit is located in the global enable register
and the word enable bit is located in the space
character preceding the word.
