Note:
Keep oscillator components close to the chip and use
short, direct traces to XTAL1, XTAL2, and V_ss. When
using crystals, C1=C2≈20pF. When using ceramic
resonators, consult the manufacturer for recommended
oscillator circuitry.

AC testing inputs are driven at 3.5 V for a logic "1" and 0.45 V for
a logic "0". Timing measurements are made at 2.0 V for a logic
"1" and 0.8 V for a logic "0".
