AnnaBridge 171:3a7713b1edbc 12 ** Abstract:
AnnaBridge 171:3a7713b1edbc 13 ** Provides a system configuration function and a global variable that
AnnaBridge 171:3a7713b1edbc 14 ** contains the system frequency. It configures the device and initializes
AnnaBridge 171:3a7713b1edbc 15 ** the oscillator (PLL) that is part of the microcontroller device.
