bit 7 bit 0

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 7-3 Unimplemented: Read as ‘0’

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’.
