Character set feature bits
Features available on the SAA56xx devices are reflected in a specific area of the Character ROM. These sections of the
Character ROM are mapped to two Special Function Registers: TXT22 and TXT12. Character ROM address 09FEH is
mapped to SFR TXT22, as shown in Table 6 and described in Table 7. Character ROM address 09FFH is mapped to
SFR TXT12, as shown in Table 8 and described in Table 9.
