(1) All typical values are V_CC = 3.3 V, T_A = 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 I_I(hold)specification for the input voltage condition 0 V < V_I< V_CC, and the I_OZspecification for the input voltage conditions V_I = 0 V or V_I = V_CC to 5.5 V. A bus-hold current with an input voltage greater than V_CC is negligible.

(4) This only applies when in a disabled state.
