Renesas PCA4738F-176A ユーザーズマニュアル

This chapter describes how to write programs with a PROM programmer. For the operation of the
PROM programmer, refer to the user's manual of the PROM programmer.

Follow these procedures (1) through (9) to write programs into the MCU.

(1) Read the program into the PROM programmer. (Offset: 8000

(2) Select the connector corresponding to the MCU. (See Section 3.2)*

2

(3) Attach the adapter to the PROM programmer. (See Section 3.3)

(4) Set the switches (SW1, SW2 and SW3). (See Section 3.4)

(5) Insert the MCU into the adapter. (See Section 3.5)

(6) Specify the programming area of the MCU using the PROM programmer. (See Section 3.6)

(7) Using the PROM programmer's erase check function, check whether data can be written into

the MCU's programming area.*

(8) Write the program into the programming area of the MCU using the PROM programmer.*

(9) Verify the programming area of the MCU using the PROM programmer to check whether the

program is written into the MCU correctly.*

1

Offset address not required when writing in M5M27C101 mode.

2

Skip this step for the PCA4738S-42A and PCA4738F-42A.

*

3

Be sure to set the programming area. Otherwise the mode's shift to the programming mode
may not be performed successfully. The erase check function etc. may not also be performed
completely.

Some PROM programmers perform these steps (7 through 9) automatically.
