Powering the MSCMMX6DZDK08AB from the OTG UBS VBUS

In the iMX Dual and Quad Applications Reference Manual is states that the stand-alone device can be powered by the OTG USB VBUS input but that it requires cooperations between the chip and the external PMIC and to consult NXP for such use.

 

We are not using a separate PMIC as we're using the MSCMMX6DZDK08AB. As this is the case;

 

Is it possible to power the unit from the VBUS supply?

 

What is necessary in the hardware to do so? i.e. what needs to be connected, enabled, held up or down to enable us to power the board from the OTG VBUS supply?

 

Thanks
