+1.8V (Core voltage) - 1.8V regulator output for digital 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 +/-
20% low ESR capacitor near this pin and connect the capacitor
from this pin to ground. X5R or X7R ceramic capacitors are
recommended since they exhibit an ESR lower than 0.1ohm at
frequencies greater than 10kHz.
