AnnaBridge 189:f392fc9709a3 17 ** Abstract:
AnnaBridge 189:f392fc9709a3 18 ** Provides a system configuration function and a global variable that
AnnaBridge 189:f392fc9709a3 19 ** contains the system frequency. It configures the device and initializes
AnnaBridge 189:f392fc9709a3 20 ** the oscillator (PLL) that is part of the microcontroller device.
