2 Interfacing to an 8-bit Processor

X31B-G-015-02

Although the S1D13706 does not directly support an 8-bit CPU, an 8-bit interface can be

achieved with minimal external logic.

Typically, the bus of an 8-bit microprocessor is straight forward with minimal CPU and

system control signals. To connect a memory mapped device such as the S1D13706, only

the write, read, and wait control signals, plus the data and address lines, need to be inter-

faced. Since the S1D13706 is a 16-bit device, some external logic is required.
