XI
Input,
Analog
N/A
Crystal pin. A 24MHz crystal is supported. The
crystal is placed across XI and XO. An external
24MHz clock source may be driven into XI in place
of a crystal.

VDDA1.8
N/A
N/A
1.8V regulator output for analog circuitry on chip.
Place a 0.1uF capacitor near this pin and connect
the capacitor from this pin to ground. In parallel,
place a 4.7uF low ESR capacitor near this pin and
connect the capacitor from this pin to ground. See
Section 6.6.1, "Internal Regulators"
.
