bogdanm 73:1efda918f0ba 18 ** Abstract:
bogdanm 73:1efda918f0ba 19 ** Provides a system configuration function and a global variable that
bogdanm 73:1efda918f0ba 20 ** contains the system frequency. It configures the device and initializes
bogdanm 73:1efda918f0ba 21 ** the oscillator (PLL) that is part of the microcontroller device.
