SAA55xx
8.6
Character set feature bits
Features available on the SAA55xx 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 . Character ROM address 09FFH is mapped to SFR TXT12 as shown in
Table .
