NuMicro M051
The outputs of internal voltage regulator, which is LDO, require an external capacitor which
should be located close to the corresponding pin. The Figure 6.2-1 shows the power architecture
of this device.

AVSS
Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 2.5V power for digital operation and I/O pins.
