3 S1D13704 Bus Interface
3.1 Host Bus Pin Connection
Interfacing to an 8-bit Processor
Issue Date: 01/02/12
This section is a summary of the host bus interface modes available on the S1D13704 and
offers some detail on the Generic #2 Host Bus Interface used to implement the interface to
an 8-bit processor.
The S1D13704 provides a 16-bit interface to the host microprocessor which may operate
in one of several modes compatible with most of the popular embedded microprocessor
families. The bus interface mode used in this example is:
• Generic #2 (this bus interface is ISA-like and can easily be modified to support an 8-bit
The following table shows the functions of each host bus interface signal.
