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 steps (1) to (7) below to write the program.
(1) Read the program into the PROM programmer.
(2) Attach the adapter to the IC socket of the PROM programmer.
See "4.2 Attaching Adapter to PROM Programmer" (page 9).
(3) Insert the MCU into the adapter.
See "4.3 Inserting MCU into Adapter" (page 10).
(4) Set the programming area with the PROM programmer.*1
See "4.6 Setting a Programming Area" (page 11).
(5) 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.
(6) Write the program into the programming area of the MCU using the PROM programmer.*2
(7) Verify the programming area of the MCU using the PROM programmer to check whether the
program has been written into the MCU correctly.*2
*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 (5) to (7) automatically.

4.2 Attaching Adapter to PROM Programmer
As shown in Figure 4.1, attach the No. 1 pin of the PCA7402E connector (standard-pitch 32-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 incorrect insertion
can cause fatal damage to the MCU.

4.3 Inserting MCU into Adapter
As shown in Figure 4.2, 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 PCA7447FP.
Be careful when attaching to the PROM programmer because incorrect insertion
can cause fatal damage to the MCU.

4.4 Precautions When Opening and Closing the IC Socket
When opening and closing the IC socket, keep the IC socket side above and horizontal. Otherwise
the inside of the IC socket may become damaged and cause an electrical insulation failure. Figure 4.3
shows the state of opening and closing the IC socket to insert the MCU.

4.5 Caution to Be Taken for This Product
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.
4.6 Setting a Programming Area
When writing and erasing programs, 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 this product. 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).
