22.2 Significant changes from the MC68HC912DG128 (non-suffix device)
22.2.1 Flash
22.2.1.1 Flash Architecture
The flash arrays are made from a new non-volatile memory (NVM)
technology. An external VFP is no longer used. Programming is now
carried out on a whole row (64 bytes) at a time. Erasing is still a bulk
erase of the entire array.
22.2.1.2 Flash Control Register
The Flash Control Register (FEECTL) is in the same location. However,
the individual bit functions have changed significantly to support the new
technology.
