CHAPTER 9FUNCTION OPTION GENERATOR
9.1 Outline of the Function Option Generator winfog
The S1C63 chip allows several hardware specifications such as I/O port functions to be selected as mask
options. This helps you to configure the hardware of your product by changing the S1C63 chip's mask
patterns according to its specifications.
The Function Option Generator winfog is the software tool for creating the files necessary to generate
mask patterns. Its graphical user interface (GUI) ensures easy selection mask options. From the files
created by winfog, Seiko Epson produces the mask patterns for the S1C63 chip.
In addition, simultaneously with this file, winfog can create mask option setup files (Motorola S2 format
data) that are required when debugging programs with the ICE. When using the ICE to debug a program,
you can download this file from the host computer, making it possible to materialize optional functions
on the ICE that are equivalent to those on the actual IC.

Fig. 9.2.1 Input/Output Files of winfog
Device information definition file (s1c63xxx.ini)
This file contains option lists for various types of microcomputers and other information. Always be
sure to use the files presented by Seiko Epson. This file is effective for only the type of microcomputer
indicated by the file name. Do not modify the contents of the file or use the file in other types of
microcomputers.
Function option document file (zzzzzzzz.fdc)
This is a text format file in which the contents of selected mask options are stored. You can read this
file into winfog and correct the already selected option settings. This file is packed along with com-
pleted other program/data files into a single file by the mask data checker winmdc, which we would
like to have presented to Seiko Epson as the mask data file. From this file, Seiko Epson will create the
mask patterns for the IC.
Function option HEX file (zzzzzzzz.fsa)
This is the Motorola S2 format file necessary to set the selected mask options in the ICE. When you
debug programs with the ICE, download this file into the ICE using debugger commands.
∗1 The "xxx" in the file name denotes the model name of a microcomputer. For the "zzzzzzzz" part, any
given file name can be specified.
∗2 For details on how to download mask options into the ICE, refer to Chapter 8, "Debugger".
