 * PORTD maps to Arduino digital pins 0 to 7
 * PORTD - The Port D Data Register - read/write
 * 
 * PORTB maps to Arduino digital pins 8 to 13 The two high bits (6 & 7) map to the crystal pins and are not usable
 * PORTB - The Port B Data Register - read/write
 * 
 * PORTD = B10101000; // sets digital pins 7,5,3 HIGH
