NOTES:
1. Typical values are at +25
°C, typical supply voltage and typical processing parameters.
2. All voltage measurements are referenced to VSS. 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 VIL and VIH as
appropriate.
3. Test conditions for itnerrupt and I/O outputs: CL = 50pF. Test conditions for the rest of the outputs: CL = 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.
5. All RX, TX, Brg Timer, I/O pins operating at 16MHz. Sclk at 35MHz and VCC at 5.6 volts. A worst case environment.
