emilmont 60:3d0ef94e36ec 12 ** Abstract:
emilmont 60:3d0ef94e36ec 13 ** Provides a system configuration function and a global variable that
emilmont 60:3d0ef94e36ec 14 ** contains the system frequency. It configures the device and initializes
emilmont 60:3d0ef94e36ec 15 ** the oscillator (PLL) that is part of the microcontroller device.
