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 9).
(3) Set the jumper switch (SW1).
For details, see "4.3 Setting Jumper Switch" (page 9).
(4) Mount the MCU into the adapter.
For details, see "4.4 Mounting an MCU into the Adapter" (page 10).
(5) Set the programming area with the PROM programmer.*1
For details, see "4.7 Setting the Programming Areas" (page 11).
(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
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.

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 4.1
and Figure 4.2.

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.

4.5 Precautions When Opening and Closing the IC Socket
When opening and closing the IC socket, hold the adapter horizontally as shown in Figure 4.4.
Otherwise the inside of the IC socket may become damaged and cause an electrical insulation failure.

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.

Chapter 5. Recommended PROM Programmers
The PROM programmers listed in Table 5.1 are recommended for the adapter PCA7427G02. Using
the actual products, we have verified that these PROM programmers can be used to write programs
without problem. Nonconformity occurring by using any other PROM programmers can not be
supported. For the latest type of PROM programmers, contact the manufacturer to confirm whether
it can be used for your product.

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 emulator and the actual MCU may differ in characteristics. Consult the user's manual of the
emulation pod to check for differences in characteristics again.
7.3 Other Precautions
7.3.1 About the Recommended PROM Programmers
Not all PROM programmers available on the market can be checked to see if they function properly.
There are several PROM programmers that we have verified to function properly. These products are
listed as recommended PROM programmers in this user's manual. Other PROM programmers may
also be used providing that you verified them to function properly.
Note: No matter which type of PROM programmer you use, it is necessary to verify completion of
programming by executing screening, etc. that are stipulated for each MCU used.
7.3.2 About Reading Out of Device Identification Code *1
Please do not use the PROM programmer's device identification code readout function.
Using this function may break down the MCU. The device identification code is included in EPROM
to indicate the manufacturer code and device code; it is not included in the MCU.
1
*
Depending on PROM programmer manufacturers, this may be referred to by another name (e.g.
ID code).
