Section 19 ROM
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 19.7 lists the registers that are present in the F-ZTAT version but not in the mask
ROM version. If a register listed in table 19.7 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
19.7 have no effect.
