2 Interfacing to an 8-bit Processor

2.1 The Generic 8-bit Processor System Bus

Although the S1D13705 does not directly support an 8-bit CPU, with minimal external logic an 8-bit interface can be achieved.

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 S1D13705, only the write, read, and wait control signals, as well as the data and address lines, need to be interfaced. Since the S1D13705 is a 16-bit device, some external logic is required.
