EEPGD
EEPGD: Flash Program/Data EEPROM Memory Select bit
1 = Accesses program space Flash memory
0 = Accesses data EEPROM memory
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
LWLO: Load Write Latches Only bit
If CFGS = 1 (Configuration space) OR CFGS = 0 and EEPGD = 1 (program Flash):
If CFGS = 0 and EEPGD = 0: (Accessing data EEPROM)
LWLO is ignored. The next WR command initiates a write to the data EEPROM.
FREE: Program Flash Erase Enable bit
If CFGS = 1 (Configuration space) OR CFGS = 0 and EEPGD = 1 (program Flash):
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.
WRERR: EEPROM Error Flag bit
1 = Condition indicates an improper program or erase sequence attempt or termination (bit is set
0 = The program or erase operation completed normally.
WREN: Program/Erase Enable bit
1 = Allows program/erase cycles
0 = Inhibits programming/erasing of program Flash and data EEPROM
WR: Write Control bit
1 = Initiates a program Flash or data EEPROM program/erase operation.
0 = Program/erase operation to the Flash or data EEPROM is complete and inactive.
RD: Read Control bit
1 = Initiates a program Flash or data EEPROM read. Read takes one cycle. RD is cleared in
0 = Does not initiate a program Flash or data EEPROM data read.
