Notes:

2. X = not applicable; H = Logic High; L = Logic Low; Hi-Z = High Impedance.

3. “Powered” state (P) is defined as 2.70 V < VDD < 5.5 V.

4. “Unpowered” state (UP) is defined as VDD = 0 V.

5. Note that an I/O can power the die for a given side through an internal diode if its source has adequate current.
