(2) This information was not available at the time of publication.
(3) This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to
another.
(4) For the total leakage current in an I/O port, please consult the I

specification for the input voltage condition 0 V < V
I
< V
CC
, and the
I

,
is negligible.
