Electrical characteristics
Table 50.
1. To sustain a voltage higher than V
2. Hysteresis voltage between Schmitt trigger switching levels. Data based on characterization, not tested in production.
3. Leakage could be higher than max. if negative current is injected on adjacent pins.
4. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This

I/O static characteristics (continued)
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
