4. How to Write the Program This chapter describes how to write programs using a PROM programmer. For details on how to operate the PROM programmer, refer to the user's manual of the PROM programmer. 4.1 Programming Procedures Follow procedures (1) to (8) to write programs into the MCU. (1) Read the program into the PROM programmer. (2) Attach the adapter to the PROM programmer. (see section 4.2) (3) Set the jumper switches (SW1, SW2 and SW3). (see section 4.4) (4) Insert the MCU into the adapte

7. Troubleshooting The table below summarizes errors to be checked carefully before you determine them to be a fault. 7.1 Errors That Occur When Writing to ROM 7.1.1 When Newly Purchased Cause Remedy See page Is the adapter attached to the correct position of the PROM 9 programmer? Programming adapter Is the MCU attached to the correct position? 10 Is the area specification set correctly? 12 PROM programmer Is the correct device selected? 13 The IC socket of the PROM programmer may be stained.

7.2 MCU Does 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
