unsigned char pin;
unsigned long i;                         

	PCONP = 0x3FE;		

	IODIR = 0xff;     	// P0.0..7 defined as Outputs 

	SPI_SPCCR = 8; 		// rate spi

	PINSEL0 = 0x5500;	// enable spi i/o 

	SPI_SPCR = 0x20; 	// master mode

  pin  = 0;

  while (1) {                             

	for(i=0;i<8;i++){

		if (pin) IOSET = 0x20; else IOCLR = 0x20; 
		pin ^= 1;


		SPI_SPDR = 0x55;// i'm expect to see some activity 

	}
