25.3 Voltage regulators
Note
The on-chip voltage regulators generate the voltages for the internal circuitry
(CPU core, clock generation circuit and peripherals), refer to Figure 25-2,
Figure 25-4 and Figure 25-6.
The regulators operate per default in all operation modes (normal operation,
HALT, IDLE, STOP, WATCH, Sub-WATCH, and during RESET).
During power save modes the voltage regulators can be optionally disabled by
setting the STBCTL register (refer to “Control registers for power save modes”
on page 157).
To stabilize the output voltage of the regulator, connect a capacitor to the
REGC pin. Refer to the Electrical Target Specification.
