Chapter 4. How to Write the Program 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. 4.1 Programming Procedure Follow steps (1) to (7) below to write the program. (1) Read the program into the PROM programmer. (2) Attach the adapter to the IC socket of the PROM programmer. See "4.2 Attaching Adapter to PROM Programmer" (page 9). (3) Insert the MCU into the adapter.

7.2 MCUs Do Not Function Normally The program operates normally on the emulator, but when the MCU that has normally been written is attached the same program does not function normally. (1) Is the offset address specified correctly when copying data into the PROM programmer? (2) In the emulator, NOPs are often inserted in the area where the program has not been read, therefore the program happens to appear functioning normally even though it may have gone wild. Check your program again. (3) The
