The MPC8314E does not require the core supply voltage (VDD and VDDC) and I/O supply voltages
(GVDD, LVDDx_ON, LVDDx_OFF, NVDDx_ON and NVDDx_OFF) to be applied in any particular
order. During the power ramp up, before the power supplies are stable, if the I/O voltages are supplied

shows the undershoot and overshoot voltages at the interfaces of the MPC8314E.
Output Impedance can also be adjusted through configurable options in DDR Control Driver Register
(DDRCDR). See the MPC8315E PowerQUICC II Pro Host Processor Reference Manual .
