Thread: Writing 16F84 EEPROM
face BY : Sebastian Garcia email (remove spam text)

Hi .....lu01tsspamSTOPspamGMX.NET ,

I suggest the following:

(assuming You're in bank0)

    movlw   0x00
    movwf   EEDATA
    movwf   EEADR

This is why your code don't work, when You did it was in bank1.

|        bsf     STATUS,RP0

    bcf INTCON,GIE    ;to disable interrupts meanwhile the write is in

|        bsf     EECON1,WREN
|        movlw   0x55
|        movwf   EECON2
|        movlw   0xAA
|        movwf   EECON2
|        bsf     EECON1,WR

    bsf INTCON,GIE;         ;to enable the interrupts.

Remember that the write time is aprox. 10 ms.

Best Regards,
