SAA55xx
8.5
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 4. Character ROM address 09FFH is mapped to SFR TXT12 as shown in
Table 6.
Table 4
U = used; X = reserved
Character ROM - TXT22 mapping
Table 5
