(1) All typical values are VCC = 3.3 V, TA = 25°C.
(2) The bus-hold maximum dynamic current requirement to switch the input from one state to another state.
(3) For the total leakage current in an I/O port, see 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. A bus-hold current with an input voltage greater than VCC is negligible.
(4) This only applies when in a disabled state.
