1.2 V/1.8 V Digital I/O Characteristics

1.2 V/1.8 V digital I/O electrical characteristics apply over the full operating temperature range, see

Section 3.1.1. The voltage thresholds for all I/Os are referenced to VDDIO, where VDDIO can be

1.2 V or 1.8 V. The supply configuration options depend on the I/O, see Register Definition.
