4. How to Write the Program
This chapter describes procedures you need to follow when writing a 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 procedures (1) to (8) to write a program.
(1) Read the program into the PROM programmer. (Offset at C0000

required)
(2) Attach the adapter to the PROM programmer. (see Section 4.2)
(3) Set the switches (JP1). (see Section 4.3)
(4) Insert the MCU into the adapter. (see Section 4.4)
(5) Set the programming area with the PROM programmer. (see Section 4.7) *
1
(6) Check to erase the programming area. *
2
Using the PROM programmer's erase check function, check whether data can be written into
the MCU's programming area.
(7) Write the program into the programming area of the MCU using the PROM programmer. *
2
(8) Verify the programming area of the MCU using the PROM programmer to check whether the
program is 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 (6) to (8) automatically.
