n REF: Analog reference voltage. This pin is connected to the AREF pin on devices

having a separate analog reference pin.

n XT1: XTAL 1 pin. The internal main clock signal to all sockets. If the XTAL1 jumper is

disconnected, this pin can be used as external clock signal.

n XT2: XTAL 2 pin. If the XTAL1 jumper is disconnected, this pin can be used for

external crystal with the XT1 pin.

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.
