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 these procedures (1) through (8) to write the program into the MCU. (1) Read the program into the PROM programmer. (2) Attach the adapter to the IC socket of the PROM programmer. For details, see "4.2 Attaching the Adapter to a PROM Programmer" (page

4.2 Attaching the Adapter to a PROM Programmer As shown in Figure 4.1, attach the pin No. 1 of the PCA7402E connector (standard-pitch 32-pin pin- header mounted) to the pin No. 1 of the IC socket of the PROM programmer. Be careful when attaching the adapter because incorrect insertion can cause fatal damage to the MCU. Figure 4.1 Attaching the adapter to a PROM programmer 4.3 Setting the Jumper Switch Set the jumper switch SW1 according to the MCU type to be programmed. For setting, see Table 4.

4.4 Mounting an MCU into the Adapter (1) As shown in Figure 4.3, set the slide bar in the center of the IC socket to the shaded area on the board. (2) As shown in Figure 4.3, mount the MCU into the IC socket with the No. 1 pin of the MCU matched to the No. 1 pin of the IC socket on the PCA7427G02. Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU.

4.6 Precautions When Handling the Adapter Do not touch the connector in the IC socket and the pins on the PROM programmer connector because dirt may cause an electrical insulation failure. When not using this product, attach the connector pins of this product to the conductive sponge as it was shipped from the factory. 4.7 Setting the Programming Areas When writing the program into the MCU, be sure to set the programming area. And also, specify its device of the PROM programmer. Table 4.2 Progra

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
