1. FT_t I/O characteristics are degraded only in VBAT mode (refer to Table 97).

2. The I/O structure options listed in this table can be a concatenation of options including the option explicitly listed. For

instance TT_a refers to any TT I/O with _a option. TT_xx refers to any TT I/O and FT_xx refers to any FT I/O.

3. The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the product reference manual for a description of GPIO

port configuration register.

4. Specified by design. Not tested in production.

5. Compensation system enabled.

6. The fall time is defined between 70% and 30% of the output waveform accordingly to I2C specification.
