bit 7

bit 0

Legend:

U = Unimplemented bit, read as ‘0’

R = Readable bit

W = Writable bit

S = Settable bit (cannot be cleared in software)

-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 Row Erase Enable bit

= Performs an erase operation on the next WR command (cleared by completion of erase operation)

= Perform write only

bit 3

WRERR:

Flash Program Error Flag bit

= A write operation is prematurely terminated (any Reset during self-timed programming in normal

operation, or an improper write attempt)

= The write operation completed

bit 2

WREN:

Flash Program Write Enable bit

= Allows write cycles to Flash program

= Inhibits write cycles to Flash program

bit 1

WR:

Write Control bit

= Initiates a program memory erase cycle or write cycle.

(The operation is self-timed and the bit is cleared by hardware once write is complete. The WR bit

can only be set (not cleared) in software.)

= Write cycle is complete

bit 0

Unimplemented:

Read as ‘0’
