The device requires its power rails to be applied in a specific sequence in order to ensure proper device
operation. These requirements are as follows for power-up:
All supplies must be at their stable values within 50 ms.

Notes:
1. The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR.
2. The drive strength of the PCI interface is determined by the setting of the PCI_GNT1 signal at reset.
3. The drive strength of the DDR interface in half-strength mode is at T

Items on the same line have no ordering requirement with respect to one
another. Items on separate lines must be ordered sequentially such that
voltage rails on a previous step must reach 90% of their value before the
voltage rails on the current step reach 10% of theirs.
In order to guarantee MCKE low during power-up, the above sequencing for
