Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
S = Bit can only be set
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
HC = Bit is cleared by hardware
bit 7
Unimplemented: Read as ‘1’
bit 6
CFGS: Configuration Select bit
1 = Access Configuration, User ID and Device ID Registers
0 = Access Flash program memory
bit 5
LWLO: Load Write Latches Only bit(3)
1 = Only the addressed program memory write latch is loaded/updated on the next WR command
0 = The addressed program memory write latch is loaded/updated and a write of all program memory write latches
will be initiated on the next WR command
bit 4
FREE: Program Flash Erase Enable bit
1 = Performs an erase operation on the next WR command (hardware cleared upon completion)
0 = Performs a write operation on the next WR command
bit 3
WRERR: Program/Erase Error Flag bit
1 = Condition indicates an improper program or erase sequence attempt or termination (bit is set automatically
on any set attempt (write ‘1’) of the WR bit).
0 = The program or erase operation completed normally.
bit 2
WREN: Program/Erase Enable bit
1 = Allows program/erase cycles
0 = Inhibits programming/erasing of program Flash
bit 1
WR: Write Control bit
1 = Initiates a program Flash program/erase operation.
The operation is self-timed and the bit is cleared by hardware once operation is complete.
The WR bit can only be set (not cleared) in software.
0 = Program/erase operation to the Flash is complete and inactive.
bit 0
RD: Read Control bit
1 = Initiates a program Flash read. Read takes one cycle. RD is cleared in hardware. The RD bit can only be set
(not cleared) in software.
0 = Does not initiate a program Flash read.
Note 1:
Unimplemented bit, read as ‘1’.
2:
The WRERR bit is automatically set by hardware when a program memory write or erase operation is started (WR = 1).
3:
The LWLO bit is ignored during a program memory erase operation (FREE = 1).
