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.
