Operating Modes and Resource Mapping
5.5.3 EEPROM Mapping
The MC68HC912D60A has 1K 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 $0C00 but can be mapped to any 4K
byte boundary within the standard 64K byte address space.

INITEE— Initialization of Internal EEPROM Position Register
$0012
EE[15:12] — Internal EEPROM map position
These bits specify the upper four bits of the 16-bit EEPROM address.
Normal modes: write once; special modes: write anytime. Read
anytime.
EEON — internal EEPROM On (Enabled)
This bit is forced to one in single-chip modes.
Read or write anytime.
0 = Removes the EEPROM from the map.
1 = Places the on-chip EEPROM in the memory map at the address
selected by EE[15:12].
