Receive-Block inner Timer-ISR:

Code:
	if (bRxFlag & RX_M_RECEIVE)		//	 receive ?
	{
          if (bRxCount == 9)		// is this the stop-Bit (9th)
          {
              bRxFlag &= ~RX_M_RECEIVE;   // receiving sequence done
	      bRxFlag |= RX_M_DATA;	// signal data
	      GICR |= 1<<INT0;  // re-enable int0 for next

	    }
	    else
            {
              bRxByte >>= 1;	  // Shift right data

/*	    if(PIND&(1<<PD2))  set bit or leave it
            {
              bRxByte |=0x80;			
	      bRxCount++;

            } */
while-Schleife:

Code:
  while(1)
  {

    if(bRxFlag & RX_M_RECEIVE)
{
    if(PIND&(1<<PD2))
    {
      PORTD |=(1<<PD4);
      bRxByte |=0x80;			
      bRxCount++;
    }
    else
    {
      PORTD &= ~(1<<PD4);
    }
  }
    }
