Kojto | 148:fd96258d940d | 14 | ** Abstract: |
Kojto | 148:fd96258d940d | 15 | ** Provides a system configuration function and a global variable that |
Kojto | 148:fd96258d940d | 16 | ** contains the system frequency. It configures the device and initializes |
Kojto | 148:fd96258d940d | 17 | ** the oscillator (PLL) that is part of the microcontroller device. |
