title: Atmel AVR Assembler time stamp counter
body: <p>Good day, everyone! 
  I try to randomize numbers on AVR Asm (atmega128). So I need initialize value at the beginning and note that for asm x86 developers use "rdtsc" instruction. Is that possible to init some random init value like rdtsc at AVR architecture? Is that possible to use different init value?
  Thanks and regards.</p>
