2.1 The Generic 8-bit Processor System Bus
Although the SED1374 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 SED1374, only
the write, read, and wait control signals, as well as the data and address lines, need to be
interfaced. Since the SED1374 is a 16-bit device, some external logic is required.
