Legend:
S = Settable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-5
Unimplemented: Read as ‘0’
bit 4
FREE: Flash Erase Enable bit
1 = Erase the program memory block addressed by TBLPTR on the next WR command (cleared by
completion of erase operation)
0 = Perform write-only
bit 3
WRERR: Flash Program Error Flag bit
1 = A write operation is prematurely terminated (any Reset during self-timed programming in normal
operation or an improper write attempt)
0 = The write operation completed
bit 2
WREN: Flash Program Write Enable bit
1 = Allows write cycles to Flash program memory
0 = Inhibits write cycles to Flash program memory
bit 1
WR: Write Control bit
1 = Initiates a program memory erase cycle or write cycle 
(The operation is self-timed and the bit is cleared by hardware once the write is complete. 
The WR bit can only be set (not cleared) in software.)
0 = Write cycle is complete
bit 0
Unimplemented: Read as ‘0’
