Note: It is recommended to add a Schottky diode (pin to ground) to analog pins which may
potentially inject negative currents.
5.3.20 I/O port characteristics
General input/output characteristics
Unless otherwise specified, the parameters given in Table 66: I/O static characteristics are
derived from tests performed under the conditions summarized in Table 18. All I/Os are
CMOS and TTL compliant.
