Legend:

R = Readable bit

S = Bit can only be set

‘1’ = Bit is set

W = Writable bit

x = Bit is unknown

‘0’ = Bit is cleared

U = Unimplemented bit, read as ‘0’

-n/n = Value at POR and BOR/Value at all other Resets

HC = Bit is cleared by hardware

bit 0

Note 1:

2:

3:

Unimplemented: Read as ‘1’

CFGS: Configuration Select bit

1 = Access Configuration, User ID and Device ID Registers

0 = Access Flash program memory

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

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

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.

WREN: Program/Erase Enable bit

1 = Allows program/erase cycles

0 = Inhibits programming/erasing of program Flash

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.

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.

Unimplemented bit, read as ‘1’.

The WRERR bit is automatically set by hardware when a program memory write or erase operation is started (WR = 1) .

The LWLO bit is ignored during a program memory erase operation (FREE = 1).
