6.3.14 I/O port characteristics
General input/output characteristics
Unless otherwise specified, the parameters given in Table 46 are derived from tests
performed under the conditions summarized in Table 21: General operating conditions. All
I/Os are designed as CMOS- and TTL-compliant (except BOOT0).
