1. Guaranteed by characterization.
2. The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the STM32F4xx reference manual for a description of
the GPIOx_SPEEDR GPIO port output speed register.
3. The maximum frequency is defined in Figure 31.
4. For maximum frequencies above 50 MHz and
VDD > 2.4 V, the compensation cell should be used.
