emilmont 78:ed8466a608b4 15 ** Abstract:
emilmont 78:ed8466a608b4 16 ** Provides a system configuration function and a global variable that
emilmont 78:ed8466a608b4 17 ** contains the system frequency. It configures the device and initializes
emilmont 78:ed8466a608b4 18 ** the oscillator (PLL) that is part of the microcontroller device.
