	  Wait states to set for NVM. Consult the datasheet as these are highly
	  dependent on the device operationg conditions.

	help
	  Enable the internal 32.768 kHz RC oscillator at startup.
	  This can then be selected as the main clock reference for the SOC.

	help
	  Enable the internal 8 MHz RC oscillator at startup.
	  This can then be selected as the main clock reference for the SOC.

	  Selects the clock that will be used for the DFLL48M's reference.
	  Main clocks, such as the CPU and AHB clocks will be derived from
	  DFLL48M.

	  This choice will leave all clocks to their current state.
	  This can be the default reset state or a state set by a bootloader.
