1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the STM32F0xxxx RM0360 reference manual for a

description of GPIO Port configuration register.

2. Guaranteed by design, not tested in production.

3. The maximum frequency is defined in Figure 17.

4. When Fm+ configuration is set, the I/O speed control is bypassed. Refer to the STM32F0xxxx reference manual RM0360

for a detailed description of Fm+ I/O configuration.
