In trying to learn how the flash in the hcs12 micro works, i found app note AN2166 which describes programming and erasing flash and eeprom memory. In the app note, it explains the use of control registries located at $00F4, $00F5, and $00F7 (FEELCK, FEEMCR, FEECTL) that are avaliable for each 2 pages of flash. However, in the documenation specific to mc9s12dg128 there is no such registries. The registries at those locatoin are reserved for the SPI block. How to I access FEELCK, FEEMCR, FEECTL?

I'm new to micros. Apologies if this is a silly quesiton.
