4. How to Write the Program
This chapter describes the programming procedure with a PROM programmer. For the operation of
the PROM programmer, refer to the instructions of the PROM programmer.
4.1 Programming Procedure
Follow these procedures (1) through (6) to write the program into the MCU.
(1) Read the program.
Read the program into the PROM programmer.
(2) Attach the adapter to the PROM programmer. (See Section 4.2)
(3) Insert the MCU into the adapter. (See Section 4.3)
(4) Check to erase the programming area.*
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 MCU.*
Write the program into the programming area of the MCU using the PROM programmer.
(6) Check to erase the programming area.*
Using the PROM programmer's erase check function, check whether data can be written into
the MCU's programming area.
*Some PROM programmers automatically perform the procedures (4) through (6) written above.
