Power Sequence
In power-up, the core voltage (1.8V) must trail the IO (2.8V) by a positive number. All
2.8V rails can be turned on at the same time or follow the power-up sequence in Figure
46: “Power Up Sequence,” on page 65.
In power down, the sequence is reversed. The core voltage (1.8V) must be turned off
before any 2.8V. Refer to Figure 47: “Power Down Sequence,” on page 66 for details.
