NOTES FOR DC ELECTRICAL CHARACTERISTICS:
1. See Figures 55 and 57 through 59 for I
2. The operating supply current is measured with all output pins disconnected;
3. The Idle Mode supply current is measured with all output pins disconnected;
4. The Power-down current is measured with all output pins disconnected;
5. The input threshold voltage of SCL and SDA (SIO1) meets the I
6. Pins of ports 1, 2, 3, and 4 source a transition current when they are being externally driven from HIGH to LOW. The transition current reaches
7. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
8. Capacitive loading on ports 0 and 2 may cause the V
9. Conditions: AV
10. The differential non-linearity (DL
11. The ADC is monotonic; there are no missing codes.
12. The integral non-linearity (IL
13. The offset error (OS
14. The gain error (G

due to external bus capacitance discharging into the port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations.
In the worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to
qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input.
