S1D15E06 Series
11. MPU INTERFACE (Reference Example)
The S1D15E06 series can be connected to the 80 series MPU and 68 series MPU. Use of a serial interface allows
operation with a smaller number of signal lines.
You can expand the display area using the S1D15E06 series as a multi-chip. In this case, the IC to be accesses can be
selected individually by the chip select signal. After initialization by the RES pin, each input terminal of the S1D15E06
series must be placed under normal control.
