The MC68HC912DT128A has 2K bytes of EEPROM which is activated
by the EEON bit in the INITEE register. Mapping of internal EEPROM is
controlled by four bits in the INITEE register. After reset EEPROM
address space begins at location $0800 but can be mapped to any 4K
byte boundary within the standard 64K byte address space. The
EEPROM block occupies the last 2K bytes of the 4K byte block.
EE[15:12] — Internal EEPROM map position
EEON — internal EEPROM On (Enabled)
These bits specify the upper four bits of the 16-bit EEPROM address.
Normal modes: write once; special modes: write anytime. Read
anytime.
Read or write anytime.
