(1) Some devices may contain additional ports with interrupts. See the block diagram and terminal function descriptions.
(2) An external signal sets the interrupt flag every time the minimum interrupt pulse duration t_(int) is met. It may be set by trigger signals
shorter than t_(int).
Leakage Current – General Purpose I/O
(P1.0 to P1.7, P2.0 to P2.7, P3.0 to P3.7, P4.0 to P4.1, PJ.0 to PJ.5, RST/NMI)
over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)

(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.
