bogdanm 0:9b334a45a8ff 18 ** Abstract:
bogdanm 0:9b334a45a8ff 19 ** Provides a system configuration function and a global variable that
bogdanm 0:9b334a45a8ff 20 ** contains the system frequency. It configures the device and initializes
bogdanm 0:9b334a45a8ff 21 ** the oscillator (PLL) that is part of the microcontroller device.
