The core supply voltage and I/O supply voltages do not have to be applied in any particular order. During
the power ramp up, before the power supplies are stable, there may be an interval when the I/O pins are
actively driven. After power is stable, as long as PORESET is asserted, most I/O pins are three-stated. To
minimize the time I/O pins are actively driven, apply core voltage before I/O voltage and assert PORESET
before the power supplies fully ramp up. In general, for a dual-supply voltage device, minimize the voltage
difference between the V
