The MPC8313E does not require the core supply voltage and IO supply voltages to be applied in any
particular order. Note that during the power ramp-up, before the power supplies are stable, there might be
a period when IO pins are actively driven. After the power is stable, as long as PORESET is asserted, most
IO pins are tri-stated. In order to minimize the time that IO pins are being actively driven, it is
