It is the designer's responsibility to verify that the power sequencing requirements
of other components are also met.
Although the non-core voltages can be powered up any time before the core
voltages, allow a reasonable time limitation (for example, 100 ms) between the
first non-core voltage power-up and the last core voltage power-up.

Power Down Sequence Requirements
There are no special requirements for the core supply to go down first, or for reset assertion when
powering down.
Although there is no limitation for power-down sequence between non-core and core
voltages, allow a reasonable time limitation (for example, 100 ms) between the first
and last voltage power-down.
