19.14 Note on Switching from F-ZTAT Version to Masked ROM Version
The masked 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 masked ROM version. If a register listed in table 19.7 is read in the masked
ROM version, an undefined value will be returned. Therefore, if application software developed
on the F-ZTAT version is switched to a masked ROM version product, it must be modified to
ensure that the registers in table 19.9 have no effect.
