The on-chip voltage regulators generate the voltages for the internal circuitry,
refer to Figure 20-1, Figure 20-2.
The regulators operate per default in all operation modes (normal operation,
HALT, IDLE1, IDLE2, STOP, Sub-clock, and during reset).
To stabilize the output voltage of the regulator, connect a capacitor to the
REGC pin. Refer to the Electrical Target Specification.
