DIFFERENCES DEPENDING ON THE MODEL
The set option content will vary depending on the model.
Here only the operation will be explained, so you should refer to the "S5U1C62xxxD Manual" concerning
the option specifications and the selection screen.
2 FOG62XX OUTLINE
2.1 Outline of Function Option Generator
With the 4-bit single-chip S1C62XXX microcomputers, the customer may select hardware options. By
modifying the mask patterns of the S1C62XXX according to the selected options, the system can be custom-
ized to meet the specifications of the target system.
The FOG62XX Option Generator (hereinafter called
FOG62XX) is a software tool for generating data files used
to generate mask patterns. It enables the customer to
interactively select and specify pertinent items for each
hardware option. From the data file created with FOG62XX,
the S1C62XXX mask pattern is automatically generated by a
general purpose computer.
The HEX file for the evaluation board (S5U1C62xxxE)
hardware option ROM is simultaneously generated with the
data file. By writing the contents of the HEX file into the
EPROM and mounting it on the evaluation board, option
functions can be executed on the evaluation board.
The program name of FOG62XX is as follows:
FOG62XX.EXE
Figure 2.1.1 shows the FOG62XX execution flow.

2.2 FOG62XX Input/Output Files
Function options can be interactively selected, so an input file need not be generated. Select the hardware
options that meet the specifications of the target system and record them in the option list (paper for
recording items in preparation for input operation; explained later).
FOG62XX outputs the following data files:
• Function option document file (C2XXYYYF.DOC)
This is a data file used to generate the mask patterns for such items as I/O ports. This file must be sent
with the completed program file. Already selected options can be modified.
• Function option HEX file (C2XXYYYF.HEX)
This is a function option file (Intel hexa format) used for evaluation board. One evaluation board
function option ROM is generated by writing this file with the ROM writer.
Remarks:
• File name "YYY" is specified for each customer by Seiko Epson.
• Combine the document files with the program files (C2XXYYYH.HEX and C2XXYYYL.HEX) using the mask
data checker (MDC62XX): copy the combined file into another diskette and submit to Seiko Epson.
• Set all unused ROM areas to FFH when writing the HEX file into the EPROM. (Refer to "S5U1C62xxxE
Manual" for the ROM installation location.)
