(3)

II applies to input-only pins and bi-directional pins. For input-only pins, II indicates the input leakage current. For bi-directional pins, II

indicates the input leakage current and off-state (Hi-Z) output leakage current.

(4)

Applies only to pins with an internal pullup (IPU) or pulldown (IPD) resistor.

(5)

IOZ applies to output-only pins, indicating off-state (Hi-Z) output leakage current.
