Chapter 4. How to Write the Program
This chapter describes procedures you need to follow when writing the program.
For details on how to operate the PROM programmer, refer to the user's manual of the PROM
programmer.
4.1 Programming Procedure
Follow these procedures (1) through (8) to write the program into the MCU.
(1) Read the program into the PROM programmer.
(2) Attach the adapter to the IC socket of the PROM programmer.
(3) Set the jumper switch (SW1).
(4) Mount the MCU into the adapter.
(5) Set the programming area with the PROM programmer.*
(6) Check to erase the programming area.*
(7) Write the program into the programming area of the MCU using the PROM programmer.*
(8) Verify the programming area of the MCU using the PROM programmer to check whether the
