1. The I/O speed is configured using the OSPEEDRy[1:0] bits. The Fm+ mode is configured in the SYSCFG_CFGR1 register.

Refer to the RM0444 reference manual for a description of GPIO Port configuration register.

2. Guaranteed by design.

3. This value represents the I/O capability but the maximum system frequency is limited to 64 MHz.

4. The fall time is defined between 70% and 30% of the output waveform, according to I2C specification.
