bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
S = Bit can only be set
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
HC = Bit is cleared by hardware
bit 7
EEPGD: Flash Program/Data EEPROM Memory Select bit
1 = Accesses program space Flash memory
0 = Accesses data EEPROM memory
bit 6
CFGS: Flash Program/Data EEPROM or Configuration Select bit
1 = Accesses Configuration, User ID and Device ID registers
0 = Accesses Flash Program or data EEPROM memory
bit 5
LWLO: Load Write Latches Only bit
If CFGS = 1 (Configuration space) OR CFGS = 0 and EEPGD = 1 (program Flash):
1 = The next WR command does not initiate a write; only the program memory latches are
updated.
0 = The next WR command writes a value from EEDATH:EEDATL into program memory latches
and initiates a write of all the data stored in the program memory latches.
If CFGS = 0 and EEPGD = 0: (Accessing data EEPROM)
LWLO is ignored. The next WR command initiates a write to the data EEPROM.
bit 4
FREE: Program Flash Erase Enable bit
If CFGS = 1 (Configuration space) OR CFGS = 0 and EEPGD = 1 (program Flash):
1 = Performs an erase operation on the next WR command (cleared by hardware after comple-
tion of erase).
0 = Performs a write operation on the next WR command.
If EEPGD = 0 and CFGS = 0: (Accessing data EEPROM)
FREE is ignored. The next WR command will initiate both a erase cycle and a write cycle.
bit 3
WRERR: EEPROM Error Flag bit
1 = Condition indicates an improper program or erase sequence attempt or termination (bit is set
automatically on any set attempt (write ‘1’) of the WR bit).
0 = The program or erase operation completed normally.
bit 2
WREN: Program/Erase Enable bit
1 = Allows program/erase cycles
0 = Inhibits programming/erasing of program Flash and data EEPROM
bit 1
WR: Write Control bit
1 = Initiates a program Flash or data EEPROM program/erase operation.
The operation is self-timed and the bit is cleared by hardware once operation is complete.
The WR bit can only be set (not cleared) in software.
0 = Program/erase operation to the Flash or data EEPROM is complete and inactive.
bit 0
RD: Read Control bit
1 = Initiates an program Flash or data EEPROM read. Read takes one cycle. RD is cleared in
hardware. The RD bit can only be set (not cleared) in software.
0 = Does not initiate a program Flash or data EEPROM data read.
