+         Use external 8 to 24 Mhz clock signal as source of main clock instead
+         of an external crystal oscillator.
+         This option disables the internal driving on the XOUT pin.
+         The external source has to provide a stable clock on the XIN pin.
+         If this option is disabled, the SoC expects a crystal oscillator
+         that needs driving on both XIN and XOUT lines.
