STM32cubeMX : if clockmux (clock configuration) is grayed, does it mean there is no clock for peripheral ?

[ranran]

Hello,

If clockmux in STM32cubeMX clock configuration is grayed, does it mean that there is no clock output and the peripheral shall not function ?

I try to use just the clock configuration generated code from stm32cubeMX and do the rest code modifications manually.

Thank you,
