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 ).
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
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
FREE: Program Flash Erase Enable bit
1 = Performs an erase operation on the next WR command (hardware cleared upon completion)
0 = Performs an 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
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.
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
0 = Does not initiate a program Flash read.

will be initiated on the next WR command
on any set attempt (write ‘ 1 ’) of the WR bit).
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.
