Description
Power supply input.
Crystal or external clock input. Functions as a crystal input or as
an external clock input. A crystal can be connected between this
pin and XTAL2 to form an internal oscillator circuit (see
This configuration requires an external 1 M resistor between the
XTAL1 and XTAL2 pins. Alternatively, an external clock can be
connected to this pin to provide custom data rates. See
“Programmable baud rate
Output of the crystal oscillator or buffered clock. (See also
XTAL1.) XTAL2 is used as a crystal oscillator output or a buffered
clock output. Should be left open if an external clock is connected
to XTAL1. For extended frequency operation, this pin should be tied
to V
