Hello, 

   I am trying to write code for a transmit and receive program in FDCAN (Classic Mode) , I have configured the PCLK1 as 170MHz,  Can I select this PCLK1 as the FDCAN clock in the FDCAN Clock Mux?

Hello,

Nothing preventing you to use FDCAN clock at 170MHz. Did you face any issue with that config: FDCAN clock source from PCLK1?
