6.14.1.4.3.3 Supply Sequencing Summary and Effects of Violations

The acceptable power-up sequence for the rails is summarized below. "Power up" here means the rail in question has reached the minimum recommended operating voltage.

CAUTION: Non-acceptable sequences leads to reliability concerns and possibly damage.
