2.2
The MPC8572E requires its power rails to be applied in a specific sequence to ensure proper device
operation. These requirements are as follows for power up:
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.
To guarantee MCKE low during power-on reset, the above sequencing for GV
concern about any of the DDR signals being in an indeterminate state during power-on reset, then the

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 DDR2 or DDR3 interface in half-strength mode is at T
