Control Register Demonstration
The bq76925 shuts down the 3.3-V level at the V3P3 pin. The Hardware IO section shows a red light next
to V3P3 to indicate that the 3.3-V level is now zero. The Evaluation Software actually monitors the V3P3
output of the bq76925 via the USB-TO-GPIO Adapter input on pin 1.

The method to wake the part from sleep is to apply a voltage, 3.3 V in the case of the bq76925EVM, to
the ALERT pin. This is accomplished easily by clicking the Wake button in the Hardware IO Section.
