Chapter 3. How to Write the Program  
This chapter describes procedures you need to follow to write the program.  
For details on how to operate the PROM programmer, refer to the user's manual of the PROM  
programmer.  
3.1 Programming Procedure  
Follow the steps (1) to (7) below 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. (See Section 3.2)  
(3) Insert the MCU into the adapter. (See Section 3.3)  
(4) Set the programming area with the PROM programmer. (See Section 3.4)  
(5) Check to erase the programming area.*  
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.*  
(7) Verify the programming area of the MCU using the PROM programmer to check whether the  
program has been written into the MCU correctly.*  
Notes:  
* 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 the steps (5) through (7) automatically.  
( 7 / 16 )  
 
3.2 Attaching the Adapter to the PROM Programmer  
As shown in Figure 3.1, 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.

As shown in Figure 3.2, 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 PCA7408.  
Be careful when attaching to the PROM programmer because incorrect insertion  
can cause fatal damage to the MCU.

CAUTION  
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 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.

etc.  
( 13 / 16 )  
 
5.2 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.  
5.3 Other Precautions  
(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.  
(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.

Depending on PROM programmer manufacturers, this may be referred to by another name (e.g.  
ID code).
