The value of these bits determines the manner in which EEPROM is erased. Bit encodings are shown
in 6.2 EEPROM Registers, page 30.
U = Unaffected by reset.
The CONFIG register is used to assign EEPROM a location in the memory map and to enable or disable
EEPROM operation. Bits in this register are user-programmed except when forced to certain values, as
noted in the following bit descriptions.
EEPROM is located at $xE00 – $xFFF, where x is the value represented by these four bits. In single-
chip and bootstrap modes, EEPROM is forced to $FE00 – $FFFF, regardless of the state of these bits.
On factory-fresh devices, EE[3:0] = $0.
0 = Normal read or program mode
1 = Erase mode
0 = EEPROM address and data bus configured for normal reads
1 = EEPROM address and data bus configured for programming or erasing
0 = Program or erase voltage to EEPROM array switched off
1 = Program or erase voltage to EEPROM array switched on
0 = COP enabled (forces reset on time-out)
1 = COP disabled (does not force reset on time-out)
