Note on Switching from F-ZTAT Version to Mask ROM Version

The mask ROM version does not have the internal registers for flash memory control that are

provided in the F-ZTAT version. Table 18.7 lists the registers that are present in the F-ZTAT

version but not in the mask ROM version. If a register listed in table 18.7 is read in the mask

ROM version, an undefined value will be returned. Therefore, if application software developed

on the F-ZTAT version is switched to a mask ROM version product, it must be modified to ensure

that the registers in table 18.7 have no effect.
