11. MPU INTERFACE (For Reference)
The S1D15300 series chips can directly connect to 8080 and 6800-series microprocessors. Also, serial interfacing requires less signal lines
between them. When multiple chips are used in the S1D15300 series they can be connected to the microprocessor and one of them can be selected
by Chip Select.
