(1) Same parametrics apply to clock input pin when crystal bypass mode is used on XT1 (XIN) or XT2 (XT2IN).
(2) Also applies to RST pin when pullup/pulldown resistor is enabled.

t
(int)
External interrupt timing
(2)
External trigger pulse width to set interrupt flag 2.2 V, 3 V 20 ns
(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 width 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 P4.7)
(P5.0 to P5.7, P6.0 to P6.7, P7.0 to P7.7, P8.0 to P8.2, PJ.0 to PJ.3, RST/NMI)

(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.
