inputs -- ports P1 and P2
PARAMETER
t_int
External interrupt timing
TEST CONDITIONS
Port P1, P2: P1.x to P2.x, external trigger pulse width to
set the interrupt flag (see Note 1)
V_CC
2.2 V/3 V

NOTE 1: The external signal sets the interrupt flag every time the minimum t_(int) parameters are met. It may be set with trigger signals shorter
than t_(int).
leakage current -- ports P1 through P8 (see Note 1 and 2)

NOTES: 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 digital port pins is measured individually. The port pin is selected for input and the pullup/pulldown resistor is disabled.
