When i've tried to write AAh to EECON my assembler writes an error i've write 0xAA instead maybe it's the problem
Your help will be appriciated

here is the code i've tried:
Code:
;movlw 0x01
;movwf EEADR
;movlw 0x06
;movwf EEDATA
;BSF STATUS, RP0 ; Bank1
;BCF INTCON, GIE ; Disable INTs.
;BSF EECON1, WREN ; Enable Write
;MOVLW 55h ;
;MOVWF EECON2 ; 55h must be written to EECON2
;MOVLW 0xAA ; to start write sequence
;MOVWF EECON2 ; Write AAh
;BSF EECON1,WR ; Set WR bit begin write
;BSF INTCON, GIE ; Enable INTs.
