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

(1) A resistive divider with two 0.5-kΩ resistors between V_CC and V_SS is used as load. The output is connected to the center tap of the
divider.
(2) The output voltage reaches at least 10% and 90% V_CC at the specified toggle frequency.
