1. Procedure (This flowchart describes the procedure used.)
Note: There are differences in function and characteristics between the LC58E76 and the LC5870 series mask ROM
2. Using the EC5876.EXE Program (Operation)
Mounted configuration
Program creation and
Data conversion and
PROM writer setup
Write data transfer
As shown in the figures below, the data to be written to the LC58E76 consists of a program data area (instruction
code area) and an option data area. The EC5876.EXE program applies a special conversion process to the option
specification data to create the option data area data.
The EC5876.EXE program converts and merges program data and option data to create the data to be written to the
LC58E76.

Write
Use the SU5870.EXE program to create the option specification data.
Use the LC5870S.EXE cross assembler to create the program. Use the dedicated development tools
for debugging.
Use the EC5876.EXE program to convert and merge the program and option data. This creates the
data to be written to the LC58E76 EPROM. (See “Using the EC5876.EXE Program”.)
Setup the PROM writer ROM type, the start and stop addresses, and other states.
(See “Use of the EPROM Writing Board”.)
Transfer the LC58E76 EPROM data created with the EC5876.EXE program to the PROM writer.
Mount the PROM writer in the LC58E76 EPROM writing board.
Mount the LC58E76 in the EPROM writing board, and write the data.
Apply an opaque seal to the LC58E76 window at the point that the data is written.
Mount the LC58E76 in the socket in the application circuit, and check that the program functions
correctly.
