Power-Up/Reset Sequence
From the application of 3.3V and 5V power to all components being out of reset typically takes 250ms.
Since the ramp up times of the 3.3 V and 5 V system power source and the onboard power source will
vary with load, the time taken for the VPX4812 to come out of reset will vary from system to system. It is
the software’s responsibility to account for this.
