(2) All typical values are at VCC = 3.3 V, TA = 25°C. (3) For the total leakage current in an I/O port, please consult the II(hold) specification for the input voltage condition 0 V < VI < VCC, and the IOZ specification for the input voltage conditions VI = 0 V or VI = VCC to 5.5 V. The bus-hold current, at input voltage greater than VCC, is negligible.
