Chapter 3. How to Write Programs

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.

3.1 Programming Procedures

Follow the steps (1) to (6) to write the program.

(1) Read the program into the PROM programmer.

(2) Attach the adapter to the PROM programmer. (see 3.2).

(3) Insert the MCU into the adapter. (see 3.3)

(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:

*1 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 etc. may not also be performed

completely.

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