g 1. Confirmation
Specify the name of the product being ordered and the type of EPROMs submitted.
Three EPROMs are required for each pattern.
If at least two of the three sets of EPROMs submitted contain identical data, we will produce masks based on this data.
We shall assume the responsibility for errors only if the mask ROM data on the products we produce differs from this
data. Thus, extreme care must be taken to verify the data in the submitted EPROMs.
Checksum code for entire EPROM
(hexadecimal notation)
In the address space of the microcomputer, the internal
ROM area is from address 408016 to FFFD16. The reset
vector is stored in addresses FFFC16 and FFFD16.
(1) Set the data in the unused area (the shaded area of the
diagram) to “FF16”.
(2) The ASCII codes of the product name “M38B57MCH–”
must be entered in addresses 000016 to 000916. And set
the data “FF16” in addresses 000A16 to 000F16.
The ASCII codes and addresses are listed to the right in
hexadecimal notation.
The option data must be entered in address 001016.
