Table 49.
1. FT = Five-volt tolerant. In order to sustain a voltage higher than V
2. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not tested in production.
3. With a minimum of 100 mV.
4. Leakage could be higher than max. if negative current is injected on adjacent pins.
5. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This

I/O static characteristics
All I/Os are CMOS and TTL compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters. The
coverage of these requirements is shown in
