; initialize EEADR registers
		movlw	high ee_stuff	;get high byte location
		movwf	EEADRH,A 	;put in EEADR high register
		movlw	lower ee_stuff	;get lower byte location
		movwf	EEADR,A 	;put in EEADR lower register

		movlw	ee_value	;get byte to be written in WREG
		movwf	EEDATA,A	;put byte in data latch

		bcf	EECON1,EEPGD,A 	;point to EEPROM data memory

		bcf	EECON1,CFGS,A 	;access EEPROM
		bsf	EECON1,WREN,A 	;enable write to data EEPROM

		bsf	EECON1,WR,A 	;start write
		bsf	INTCON,GIEH,A 	;re-enable interrupts

		bcf	EECON1,WREN,A 	;disable writes once done
