Was bringt das?:
Code:
; Reset and Interrupt vector	; VNr.  Beschreibung
	rjmp	main	; 1   POWER ON RESET
	reti		; 2   Int0-Interrupt
	reti		; 3   Int1-Interrupt
	reti		; 4   TC2 Compare Match
	reti		; 5   TC2 Overflow
	reti		; 6   TC1 Capture
	reti		; 7   TC1 Compare Match A
	reti		; 8   TC1 Compare Match B
	reti		; 9   TC1 Overflow
	reti		; 10  TC0 Overflow
	reti		; 11  SPI, STC Serial Transfer Complete
	reti		; 12  UART Rx Complete

Code:
ldi temp, LOW(RAMEND)      ;LOW-Byte der obersten RAM-Adresse 
      out SPL, temp 
      ldi temp, HIGH(RAMEND)      ;HIGH-Byte der obersten RAM-Adresse 
      out SPH, temp
