I've created new STM32H753IIKx project with CubeMX(Ver4.26.0), and changed the I2C1/I2C2 setting into "I2C" from "Disable" in Pinout tab.
And, switch to Configuration tab, open the I2C1 Configuration, move to GPIO Settings tab, I can modify the Fast Mode setting to "Enable" from "Disable" on each PB8/PB9.
However, in the I2C2 Configuration case, I cannot modify the Fast Mode setting that shows "n/a".
Does this mean that I2C2 cannot be used as Fast Mode ?
Is there difference between I2C1 and I2C2 from functionality point of view ?
