When a WRERR error occurs, the EEPGD and CFGS bits are not cleared. This allows tracing of the error
condition.
Unimplemented: Read as ‘0’
WPROG: One Word-Wide Program bit
1 = Program 2 bytes on the next WR command
0 = Program 64 bytes on the next WR command
FREE: Flash Erase Enable bit
1 = Performs an erase operation on the next WR command (cleared by completion of erase operation)
0 = Perform write-only
WRERR: Flash Program Error Flag bit
1 = A write operation is prematurely terminated (any Reset during self-timed programming in normal
0 = The write operation completed
WREN: Flash Program Write Enable bit
1 = Allows write cycles to Flash program memory
0 = Inhibits write cycles to Flash program memory
WR: Write Control bit
1 = Initiates a program memory erase cycle or write cycle
0 = Write cycle is complete
Unimplemented: Read as ‘0’
operation, or an improper write attempt)
(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.)
