I have brown-out on and i have tried several settings, but it dosn't help. I believe I need to use WREN and write together. Heres a direct quote from the datasheet.

"There are conditions when the device may not want to
write to the data EEPROM memory. To protect against
spurious EEPROM writes, various mechanisms have
been implemented. On power-up, the WREN bit is
cleared. In addition, writes to the EEPROM are blocked
during the Power-up Timer period (TPWRT,
parameter 33).

The write initiate sequence and the WREN bit together
help prevent an accidental write during brown-out,
power glitch or software malfunction."

I believe this is exactly what I need. But its all in ASM.

CLRF EEADR ; Start at address 0
CLRF EEADRH ;
BCF EECON1, CFGS ; Set for memory
BCF EECON1, EEPGD ; Set for Data EEPROM
BCF INTCON, GIE ; Disable interrupts
BSF EECON1, WREN ; Enable writes
Loop ; Loop to refresh array
BSF EECON1, RD ; Read current address
MOVLW 55h ;
MOVWF EECON2 ; Write 55h
MOVLW 0AAh ;
MOVWF EECON2 ; Write 0AAh
BSF EECON1, WR ; Set WR bit to begin write
BTFSC EECON1, WR ; Wait for write to complete
BRA $-2
INCFSZ EEADR, F ; Increment address
BRA LOOP ; Not zero, do it again
INCFSZ EEADRH, F ; Increment the high address
BRA LOOP ; Not zero, do it again
BCF EECON1, WREN ; Disable writes
BSF INTCON, GIE ; Enable interrupts

The question is how do I only write my two Variables to eeprom if all is well (within voltage range). One of these variables is a byte and the other is a word.

As to your questions, This is a modification of a machine. I can't remove any capacitors from the power supply like i could in the other project that had the same issue. I would like to resolve this problem once and for all, not for just this project but also for all projects to come.

I do write to the eeprom. but i do not want to write if the system is powering down or up.

Thank you for your time....
