(1) The leakage current is measured with VSS or VCC applied to the corresponding pins, unless otherwise noted.
(2) The leakage of the digital port pins is measured individually. The port pin is selected for input and the pullup or pulldown resistor is
disabled.

(1) The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop
specified.
(2) The port can output frequencies at least up to the specified limit and might support higher frequencies.
