Legend:
S = Settable bit (cannot be cleared in software)
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 7-6
Unimplemented:
Read as ‘0’
bit 5
WPROG:
One Word-Wide Program bit
1
= Program 2 bytes on the next WR command
0
= Program 64 bytes on the next WR command
bit 4
FREE:
Flash Erase Enable bit
1
= Perform an erase operation on the next WR command (cleared by hardware after completion of erase)
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 is complete
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’
