Power-up Requirements
Power supply sequencing is not required if you are configuring
VDDQ=3.3volts and all power supplies pins are connected to
the same 3.3 volt power supply.
Power supply sequencing is required if you are configuring
VDDQ=1.5volts. Power must be applied in the following
sequence: VCC (3.3) followed by VDDQ (1.5). Power supply
ramping may occur simultaneously as long as the VCC/VDDQ
relationship is maintained.
