Microcontroller Interfacing
The 80C51 communicates with the peripheral functions using Special Function Registers which are addressed as RAM locations. The registers in the
teletext decoder appear as normal SFRs in the microcontroller memory map, but are written to using an internal serial bus. The SFR map is given in
Section 7.4.1 and the SFR bit description is given in Section 7.4.2.
