1. If V
2. TTa = 3.3 V tolerant I/O directly connected to ADC; TC = standard 3.3 V I/O.
3. FT = 5 V tolerant.
4. With a minimum of 100 mV.
5. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not tested in production.
6. Leakage could be higher than the maximum value, if negative current is injected on adjacent pins.
7. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
8. Guaranteed by design, not tested in production.
