Renesas PCA7435SPG02 User Manual

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.

Follow these procedures (1) through (8) to write the program into the MCU.

Notes

*1 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 and others may not also be performed
completely.

*2 Some PROM programmers perform the steps (6) to (8) automatically.

(1) Read the program into the PROM programmer.

(4) Mount the MCU into the adapter.

For details, see "4.4 Mounting an MCU into the Adapter" (page 12).

(5) Set the programming area with the PROM programmer.*

1

For details, see "4.6 Setting the Programming Area" (page 13).

(6) Check to erase the programming area.*

2

Using the PROM programmer's erase check function, check whether data can be written into the
MCU's programming area.

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

2

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

program has been written into the MCU correctly.*

(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 10).

(3) Set the switch on the PROM programmer.

For details, see "4.3 Setting the Switch" (page 11).
