Note: It is recommended to add a Schottky diode (pin to ground) to analog pins which may
potentially inject negative currents.
6.3.16 I/O port characteristics
General input/output characteristics
Unless otherwise specified, the parameters given in Table 5 4 are derived from tests
performed under the conditions summarized in Table 14. All I/Os are CMOS and TTL
compliant.
