A funguje to kdyz, budete cekat podle datasheetu ?

    bsf STATUS, RP0
    bcf INTCON, GIE
    bcf EECON1, EEIF
    bsf EECON1, WREN
    movlw 55H  ;
    movwf  EECON2  ;
    movlw 0AAH  ;
    movwf  EECON2  ;
    bsf  EECON1, WR
btfss EECON1,EEIF
goto $-1
    bcf EECON1, WREN
    bcf STATUS, RP0

EEPROM u subj. Kdyz vse bezi na 4Mhz, tak to chodi, ale na 18Mhz se vzdy
zapise na danou adresu FF. Pro zapis pouzivam toto:
