DC-DC Regulator Voltage Control Register (02h)
This register controls the output voltage of the DC-DC
PWM/PFM Regulator. The DC-DC Regulator employs a
dual scale voltage step size to cover a wide range of
output voltages from 0.8V to 1.8V. From 0.8V to 1.2V a
step size of 25mV allows maximum power saving when
the Processor Core is placed into a light load state. From
1.2V to 1.8V, a step size of 50mV provides a wide range
of output voltages for power system flexibility.
