EEPGD
: Program/Data EEPROM Select bit
1
= Accesses program memory
0
= Accesses data memory
Reads ‘0’ after a POR; this bit cannot be changed while a write operation is in progress.
Unimplemented:
Read as '0'
FREE:
EEPROM Forced Row Erase bit
1
= Erase the program memory row addressed by EEADRH:EEADR on the next WR command
0
= Perform write only
WRERR:
EEPROM Error Flag bit
1
= A write operation is prematurely terminated
(any MCLR or any WDT Reset during normal operation)
0
= The write operation completed
WREN:
EEPROM Write Enable bit
1
= Allows write cycles
0
= Inhibits write to the EEPROM
WR:
Write Control bit
1
= Initiates a write cycle. The bit is cleared by hardware once write is complete. The WR bit
can only be set (not cleared) in software.
0
= Write cycle to the EEPROM is complete
RD:
Read Control bit
1
= Initiates an EEPROM read, RD is cleared in hardware. The RD bit can only be set (not
cleared) in software.
0
= Does not initiate an EEPROM read

Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
S = Set only
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
x = Bit is unknown
