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).
