ROM versions. When pre-producing an application set with the flash memory version and then
mass-producing it with the mask ROM version, be sure to conduct sufficient evaluations for the
commercial samples (not engineering samples) of the mask ROM versions.
The same capacity as the mask ROM versions can be specified by means of the internal memory size
switching register (IMS).
The regulator cannot be used in (A1) grade products and (A2) grade products.
