1. Like power supplies must be tied together. For example, if VCCIO and VCC are both 2.5V, they must also be the same supply. 3.3V VCCIO
and 1.2V VCCIO should be tied to VCCAUX or 1.2V VCC respectively.
2. See recommended voltages by I/O standard in subsequent table.
3. VCC must reach minimum VCC value before VCCAUX reaches 2.5V.

1. Insensitive to sequence of VCC, VCCAUX, and VCCIO. However, assumes monotonic rise/fall rates for VCC, VCCAUX, and VCCIO.
2. 0 ≤ VCC ≤ VCC (MAX), 0 ≤ VCCIO ≤ VCCIO (MAX) and 0 ≤ VCCAUX ≤ VCCAUX (MAX).
3. IDK is additive to IPU, IPD or IBH.
