RST
Reset Input. This pin contains a Schmitt voltage input to recognize external active
high reset inputs. The pin also employs an internal pulldown resistor to allow for a
combination of wired OR external reset sources. An RC is not required for power-up,
as the device provides this function internally.

XTAL1
Crystal Oscillator Pins. XTAL1 and XTAL2 provide support for parallel-resonant,
AT-cut crystals. XTAL1 acts also as an input if there is an external clock source in
place of a crystal. XTAL2 is the output of the crystal amplifier.
