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 21. 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. |
