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
GVDD is required. If there is no concern about any of the DDR signals
being in an indeterminate state during power-up, then the sequencing for
GVDD is not required.
