Microcontrollers for NTSC TVs with On-Screen
Display (OSD) and Closed Caption (CC)
P8xCx70 family
18.7.1
S
CREEN COLOUR DISPLAY AREA
The screen colour display area starts with a fixed offset of
8
μ
s from the leading edge of the horizontal sync pulse in
the horizontal direction. A vertical offset is not necessary.

EXT DISPLAY AREA
Table 69
Text display area
The text area can be defined to start with an offset in both
the horizontal and vertical direction. The horizontal offset
is set in the Text Horizontal Position Register (see
Section 18.9.3). The offset is in full width characters
(1 to 64 characters) and quarter characters for fine setting
(0 to 3 quarters). The vertical offset is set in the Text
Vertical Position Register (see Section 18.9.2). The offset
is done in number of lines (0 to 63).

The values ‘000000’ to ‘000011’ will result in a
corrupted offset.

Horizontal
Up to 48 full sized characters per row.
Start position setting from 3 to 64
characters from the leading edge of
HSYNC. Fine adjustment in quarter
characters.
208 lines (nominal 38 to 245). Start
position setting from leading edge of
vertical sync, legal values are 4 to 64
lines.

Table 71
Text area fine offset
Table 72
Text vertical position
The width of the text area is defined by setting the end
character value (1 to 64 characters). This number
determines where the background colour will end if set to
extend to the end of the row. It will also terminate the
character fetch process thus eliminating the necessity of a
row end attribute. This entails however writing to all
positions.
The text area end is set by the TAE0 to TAE5 bits in the
Text Area End Register (see Section 18.9.5). The width is
the difference between the horizontal offset and the end
value and is always as a number of full width characters
(0 to 48 valid range). The quarter character offset in the
Text Horizontal Position Register is also valid for the end
position.
