• Description: Cmos 8-bit Single Chip Microcomputer
• Manufacturer: Epson Electronics America, Inc.

When submitting mask data to Seiko Epson, you should use the mdc88112 and it must include program
data in the mask data, even if you use the S1C88112 in the MPU mode that does not need to make a mask
for internal ROM; it needs masking only for the mask option (I/O settings, etc.).

Program data HEX file to be packed/unpacked
mdc88112 executes the following processing for the program data file generated by the
user.
Since the built-in ROM capacity of the S1C88112 is 12K bytes (000000H–002FFFH), the
packing/unpacking processing by the mdc88112 is done for only the 12K bytes area from
the top of program data that can be masked into ROM.
When packing, the mdc88112 extracts the part (12K bytes) to be masked into the S1C88112
built-in ROM and generates the pack data for generating the mask. When restoring the
program data by unpacking, only 12K bytes of program data generated as the pack data is
restored. Be careful: the program data exceeding 12K bytes becomes invalid in the
mdc88112 if the program data created by the user exceeds 12K bytes.
