Notes:
(1) VDD must be lowered to 0.2V in order to reset the device.
(2) VIL min and VIH max are reference values only and are not tested.
(3) This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
(4) The output current must be limited to a maximum 25mA per each I/O; the total current sunk by all I/O must be limited to 200mA (or 100mA
for eight I/Os)
