There are differences in noise immunity and noise radiation between the flash memory and mask 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 version. 2. When replacing the flash memory versions with mask ROM versions, write the same code in the empty area of the internal ROM. |
