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