Chapter 3. How to Write Programs 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. 3.1 Programming Procedures Follow the steps (1) to (6) to write the program. (1) Read the program into the PROM programmer. (2) Attach the adapter to the PROM programmer. (see 3.2). (3) Insert the MCU into the adapter. (see 3.3) (4) Using the PROM programmer's erase check function, che

3.2 Attaching the Adapter to a PROM Programmer As shown in Figure 3.1, attach the No. 1 pin of the PCA7402D connector (standard-pitch 28-pin pin- header mounted) to the No. 1 pin of the IC socket of the PROM programmer. Be careful when attaching to the PROM programmer because an incorrect insertion can cause fatal damage to the MCU.

(2) For PCA7442FPG02 As shown in Figure 3.3, insert 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 PCA7442FPG02. Be careful when attaching to the PROM programmer because an incorrect insertion can cause fatal damage to the MCU. Top view Figure 3.3 Inserting an MCU (PCA7442FPG02) (3) For PCA7442SP As shown in Figure 3.4, insert 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 PCA744

CAUTION Cuation for the Slide Bar of the PCA7441: • There is a slide bar in the center of the PCA7441. Set this slide bar to the shaded area (factory-setting). Otherwise the MCU may cause a break because of an electrical insulation failure. Caution to Be Taken for Handling an MCU: • Do not touch the connector in the IC socket and the pins on the PROM programmer connector. Otherwise it can cause an electrical insulation failure because of dirt. When not using, attach the connector pins of this pr
