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 reference manual RM0440 "STM32G4 Series advanced Arm®-

based 32-bit MCUs" for a description of GPIO Port configuration register.

2. Guaranteed by design.

3. This value represented the I/O capability but maximum system frequency is 170 MHz.

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

5. The maximum frequency is defined with the following conditions:

- (Tr+ Tf) ≤ 2/3 T.

- 45%<Duty cycle<55%
