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 E/W control bit located in register TXT4.
An example of the character set selection and definitions is show in Table 27.
An example of the national option reference table is shown in Table 28. Only a certain number of national
options will be relevant for each of the Character Sets.
