high current in the internal ESD protection diodes. The rise times on the power supplies should be slower than 500 us to avoid
turning on the internal ESD protection clamp diodes.

There is no limit on how long after IV
not lag EV
ESD protection diodes. There are no requirements for the fall times of the power supplies.
The recommended power down sequence is as follows:

are powered down first, sense circuits in the I/O pads cause all output drivers to be in a high impedance state.
In this table and throughout this document, a single signal within a group is designated
without square brackets (i.e., A23), while designations for multiple signals within a group
use brackets (i.e., A[23:21]) and is meant to include all signals within the two bracketed
numbers when these numbers are separated by a colon.
The primary functionality of a pin is not necessarily its default functionality. Pins that are
muxed with GPIO default to their GPIO functionality.
