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.

Follow these procedures (1) through (6) to write the program into the MCU.

(1) Mount the MCU into the adapter (see section 3.3).

(2) Attach the adapter to the IC socket of the PROM programmer (see section 3.2).

(3) Set the programming area with the PROM programmer (see section 3.4).

(4) Using the PROM programmer's erase check function, check whether data can be written into

the MCU's programming area.*

(5) Write the program into the programming area of the MCU using the PROM programmer.*

(6) Verify the programming area of the MCU using the PROM programmer to check whether the

program has been written into the MCU correctly.*

Notes

* Be sure to set the programming area. Otherwise the mode's shift to the programming mode may

not be performed successfully. The erase check function and others may not also be performed
completely.

* Some PROM programmers perform the steps (4) to (6) automatically.
