Power supply input.

XTAL1

Crystal or external clock input. Functions as a crystal input or as an

external clock input. A crystal can be connected between XTAL1 and

XTAL2 to form an internal oscillator circuit (see Figure 13). Alternatively,

an external clock can be connected to this pin to provide custom data

rates.

XTAL2

Output of the crystal oscillator or buffered clock. (See also XTAL1.)

XTAL2 is used as a crystal oscillator output or a buffered clock output.
