How can I Getting the microcontroller clock frequency. So, I could use to change the CAN or LIN baud
which device do you use?
By default, the device is running at system clock frequency given by internal RC oscillator 16MHz. Then it's a matter of your software. Take a look at this example to see how to initialize mode and clocks:
Here you can find PLL calculator which can help you to do own configuration:
If you want to confirm the system clock frequency by measurement, use CLKOUT pin (must be configured by SW, see reference manual for more details).
