n REF: Analog reference voltage. This pin is connected to the AREF pin on devices
n XT1: XTAL 1 pin. The internal main clock signal to all sockets. If the XTAL1 jumper is
n XT2: XTAL 2 pin. If the XTAL1 jumper is disconnected, this pin can be used for
The headers for the LEDs and switches use the same pinout as the I/O port headers.
The pinout of the switch header is explained in Figure 3-7 and the pinout for the LED
header is explained in Figure 3-8. The square marking indicates pin 1.
