3.2 Other Precautions
3.2.1 About 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 the
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 microcomputer used.
3.2.2 About Reading Out of the 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).
