inputs Px.x, TAx

	PARAMETER	TEST CONDITIONS	VCC	MIN	TYP MAX	UNIT
		Port P1, P2: P1.x to P2.x,	2.2 V/3 V	1.5		cycle
t(int)	External interrupt timing
		External trigger signal for the interrupt flag,	2.2 V	62		ns
		(see Note 14)	3 V	50
			2.2 V/3 V	1.5		cycle
t(cap)	Timer_A, capture timing	TA0, TA1, TA2. (see Note 15)
			2.2 V	62		ns
			3 V	50

NOTES: 14. The external signal sets the interrupt flag every time the minimum tint cycle and time parameters are met. It may be set even with trigger signals shorter than tint. Both the cycle and timing specifications must be met to ensure the flag is set. tint is measured in MCLK cycles.

15.The external capture signal triggers the capture event every time when the minimum tcap cycles and time parameters are met. A capture may be triggered with capture signals even shorter than tcap. Both the cycle and timing specifications must be met to ensure a correct capture of the 16-bit timer value and to ensure the flag is set.
