NOTES:
1. Typical values are at +25
°
C, typical supply voltage and typcial processing parameters.
2. All voltage measurements are referenced to V
SS
. For testing, all inputs swing between 0.4V and 2.4V with a transition time of 10ns
maximum. For X1/CLK, this swing is between 0.4V and 4.4V. All time measurements are referenced at input voltages of V
IL
and V
IH
as
appropriate.
3. Test conditions for interrupt and I/O outputs: C
L
= 50pF. Test conditions for the rest of the outputs: C
L
= 60pF.
4. Simultaneous switching more than 6 I/O port pins from 5 volts to 0 volts at full capacitive load may ground bounce on the output pins up to
0.95 volts.
