Selects the clock source for HFCLK. Note that selecting an oscillator that is disabled will cause the system clock to stop.
Check the status register and confirm that oscillator is ready before switching. If the system can deal with a temporarily
stopped system clock, then it is okay to switch to an oscillator as soon as the status register indicates that the oscillator has
been enabled successfully.
