3.6.1Using the Power Management Features

PF14-PF12 allow you to program the core voltage of the DSP. The default core voltage is 1.5V. Table 3-4gives 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.

Table 3-4: Power Management PF Settings
