    FX3 Enumeration with External Power



      So I'm looking at developing a board that uses the FX3 chip and FPGA in a Slave FIFO arrangement. The main voltage regulators that generate the 3.3V and 1.2V for my circuit will be powered by an external power source. This power source will be switched on, when the 5V is detected on the VBUS line. My question is... Will the FX3 be able to configure its self to the bootloader, if the power supply for the VIO's and VDD's is from the external source? Bearing in mind that this power would reach the FX3 probably around a second after the FX3 receives the power on the VBUS line.
