3.6.1 Using the Power Management Features
PF14-PF12 allow you to program the core voltage of the DSP. The default core
voltage is 1.5V. Table 3-4 gives the value of the core voltage corresponding to
the state of these PFs.
When lowering the core voltage of the DSP, the frequency of the DSP must be
taken into consideration. As you lower the core voltage of the DSP, the frequency
the core is running at must be decrease.
