      Electrical Characteristics
      2.1.3
      Output Driver Characteristics
      Table 3 provides information on the characteristics of the output driver strengths.
      2.2
      Power Sequencing
      The device requires its power rails to be applied in specific sequence in order to ensure proper device
      operation. These requirements are as follows for power up:
      1. VDD, AVDD_n, BVDD, LVDD, SVDD, OVDD, TVDD, XVDD
      2. GVDD
      Note that all supplies must be at their stable values within 50 ms.
      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 GV
      DD 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.
      From a system standpoint, if any of the I/O power supplies ramp prior to the VDD core supply, the I/Os
      associated with that I/O supply may drive a logic one or zero during power-up, and extra current may be
      drawn by the device.

      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.
