Please note the following when converting the F-ZTAT application software to the mask-ROM
versions.
The values read from the internal registers for the flash ROM of the mask-ROM version and F-
ZTAT version differ as follows.
Note: This difference applies to all the F-ZTAT versions and all the mask-ROM versions that have

different ROM size.
2. Auto-programming should be performed once only on the same address block.
Notes when Converting the F-ZTAT Application Software to the
Mask-ROM Versions
For other chips for which the erasure history is unknown, it is recommended that auto-
erasing be executed to check and supplement the initialization (erase) level.
Additional programming cannot be performed on previously programmed address
blocks.
