AnnaBridge 171:3a7713b1edbc 23 ** Abstract:
AnnaBridge 171:3a7713b1edbc 24 ** Provides a system configuration function and a global variable that
AnnaBridge 171:3a7713b1edbc 25 ** contains the system frequency. It configures the device and initializes
AnnaBridge 171:3a7713b1edbc 26 ** the oscillator (PLL) that is part of the microcontroller device.
