set interrupt flag
(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)
.

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) The maximum total current, I
(OHmax)
, for all outputs combined should not exceed ±20 mA to hold the maximum voltage drop specified.
See Recommended Operating Conditions for more details.
(2) The maximum total current, I
(OLmax)
, for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop specified.
(3) The maximum total current, I
(OLmax)
, for all outputs combined should not exceed ±100 mA to hold the maximum voltage drop specified.
