19.10.1 CHARACTER MATRICES
The character matrices that can be accommodated in both
display modes are:
(H
× V × planes) 12 × 9 × 1, 12 × 10 × 1, 12 × 13 × 1,
12
× 16 × 1.
These modes allow two colours per character position.
In CC mode two additional character matrices are
available to allow four colours per character.
(H
× V × planes) 12 × 13 × 2, 12 × 16 × 2.
The characters are stored physically in ROM in a matrix of
size either 12
× 10 or 12 × 16.
19.10.2 CHARACTER SET SELECTION
Four character sets are available in the device. A set can
consist of alphanumeric characters as required by the
WST or US Closed Captioning, Customer definable
On-Screen Display characters, and Special Graphic
characters.
CC: Only a single character set can be used for display
and this is selected using the Basic Set selection
TXT18.BS<1:0>. When selecting a character set in
CC mode the Twist Set selection TXT19.TS<1:0> should
be set to the same value as TXT18.BS<1:0> for correct
operation.
TXT: Two character sets can be displayed at once. These
are the basic G0 set or the alternative G0 set (Twist Set).
The basic set is selected using TXT18.BS<1:0>.
The alternative/twist character set is defined by
TXT19.TS<1:0>. Since the alternative character set is an
option it can be enabled or disabled using TXT19.TEN,
and the language code that is defined for the alternative
set is defined by TXT19.TC<2:0>.
The National option table is selected using
TXT18.NOT<3:0>. A maximum of 31 National option
tables can be defined when combined with the
EAST/WEST control bit located in register TXT4.
An example of the character set selection and definitions
is show in Table 28.
An example of the National option reference table is shown
in Table 29. Only a certain number of national options will
be relevant for each of the Character sets.
