Read: Anytime
Write: The EEON bit can be written to any time on all devices. Bits E[11:15] are “write anytime in all
modes” on most devices. On some devices, bits E[11:15] are “write once in normal and emulation modes
and write anytime in special modes”. See device overview chapter to determine the actual write access
rights.
This register initializes the position of the internal EEPROM within the on-chip system memory map.

Internal EEPROM Map Position — These bits determine the upper five bits of the base address for the system’s
internal EEPROM array.
Enable EEPROM — This bit is used to enable the EEPROM memory in the memory map.
0 Disables the EEPROM from the memory map.
1 Enables the EEPROM in the memory map at the address selected by EE[15:11].
