  8. Contoh Software Assembler AVR ;My Very First AVR Project .include "8535def.inc" ;Includes the 8515 definitions file .def Temp = R16 ;Gives "Defines" Register R16 the name Temp .org 0x0000 ;Places the following code from address 0x0000 rjmpRESET ;Take a Relative Jump to the RESET Label RESET: ;Reset Label ldiTemp, 0xFF ;Store 255 in R16 (Since we have defined R16 = ; Temp) out DDRB, Temp ;Store this value in The PORTB Data direction ;Register Loop: ;Loop Label out PORTB, Temp ;Write all highs (255 decimal) to PORTB dec Temp ;Decrement R16 (Temp) rjmp Loop ;Take a relative jump to the Loop label
