+1.8 V from internal core regulator.
Both pins must be connected
together externally. Each pin requires
a 0.01uF decoupling capacitor. In
addition, pin 3 requires a bulk 10uF
capacitor (<2 Ohm ESR) in parallel.

regulator. This pin must be connected
to a 10uF capacitor (<2 Ohm ESR), in
parallel with a 0.01uF capacitor to
ground. See
