1 = Erase the program memory row addressed by TBLPTR on the next WR command (cleared
0 = Perform write only
WRERR: Flash Program/Data EEPROM Error Flag bit
1 = A write operation is prematurely terminated (any Reset during self-timed programming in
0 = The write operation completed
WREN: Flash Program/Data EEPROM Write Enable bit
1 = Allows write cycles to Flash program/data EEPROM
0 = Inhibits write cycles to Flash program/data EEPROM
WR: Write Control bit
1 = Initiates a data EEPROM erase/write cycle or a program memory erase cycle or write cycle
0 = Write cycle to the EEPROM is complete
RD: Read Control bit
1 = Initiates an EEPROM read (Read takes one cycle. RD is cleared in hardware. The RD bit can

only be set (not cleared) in software. RD bit cannot be set when EEPGD = 1 or CFGS = 1.)
When a WRERR occurs, the EEPGD and CFGS bits are not cleared.
This allows tracing of the error condition.
