ODD — Program Odd Rows (TEST)
EVEN — Program Even Rows (TEST)
ROW and BYTE — Row Erase Select Bit and Byte Erase Select
The value of these bits determines the manner in which EEPROM is erased. Bit encodings are shown
in 6.2 EEPROM Registers, page 30.
ERASE — Erase/Normal Control for EEPROM
0 = Normal read or program mode
1 = Erase mode
EELAT — EEPROM Latch Control
0 = EEPROM address and data bus configured for normal reads
1 = EEPROM address and data bus configured for programming or erasing
EEPGM — EEPROM Program Command
0 = Program or erase voltage to EEPROM array switched off
1 = Program or erase voltage to EEPROM array switched on
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.
EE[3:0] — EEPROM Map Position
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.
Bit 3 — Not implemented. Reads always return one and writes have no effect.
NOCOP — COP System Disable
0 = COP enabled (forces reset on time-out)
1 = COP disabled (does not force reset on time-out)
PPROG — EEPROM Programming Control
