The minimum supply voltage for the ADSP-21065L is 3.0V. An ADM708T is used to monitor
the supply voltage and holds the processor in reset if the power supply’s voltage is below 3.08V.
The board hardware may also be reset via the push button that is connected to this part. For more
information, see “User Push-button Switches” section in this Chapter.
