STM32 Nucleo support for 1.8V

[smul]

Hi

I'm using the STM32H755ZI board which has the option for 1.8V DVDD (using JP5).

Does switching DVDD to 1.8V from 3.3V limit the functionality of the board in any way ?

Are the interfaces (CAN, I2C, SPI, UART etc) still functional at 1.8V ? 

Thanks in advance for any help

E,g,USB needs 3 V minumum
