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

WR: Write Control bit (program or erase)
1 = Initiates a data EEPROM erase or write cycle (can be set, but not cleared in software)
0 = Write cycle is complete (cleared automatically by hardware)
WREN: Write Enable bit (erase or program)
1 = Enables an erase or program operation
0 = No operation allowed (device clears this bit on completion of the write/erase operation)
WRERR: Flash Error Flag bit
1 = A write operation is prematurely terminated (any MCLR or WDT Reset during programming
operation)
0 = The write operation completed successfully
PGMONLY: Program Only Enable bit
1 = Write operation is executed without erasing target address(es) first
0 = Automatic erase-before-write
Write operations are preceded automatically by an erase of the target address(es).
Unimplemented: Read as ‘0’
ERASE: Erase Operation Select bit
1 = Performs an erase operation when WR is set
0 = Performs a write operation when WR is set
NVMOP<5:0>: Programming Operation Command Byte bits
Erase Operations (when ERASE bit is ‘1’):
011010 = Erase 8 words
011001 = Erase 4 words
011000 = Erase 1 word
0100xx = Erase entire data EEPROM
Programming Operations (when ERASE bit is ‘0’):
0010xx = Write 1 word
