Procedure
6. Port ADx 375
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.
The Flash Control Register (FEECTL) is in the same location. However,
the individual bit functions have changed significantly to support the new
technology.
Programming of the flash is greatly simplified over previous HC12s. The
read / verify / re-pulse programming algorithm is replaced by a much
simpler method.
