|

* @brief External oscillator and clock configuration |
||||
* |
||||
* For selection of the used CORECLOCK, we have implemented two choices: |
||||
* |
||||
* - usage of the PLL fed by the internal 8MHz oscillator divided by 8 |
||||
* - usage of the internal 8MHz oscillator directly, divided by N if needed |
||||
* |
||||
* |
||||
* The PLL option allows for the usage of a wider frequency range and a more |
||||
* stable clock with less jitter. This is why we use this option as default. |
||||
* |
||||
* The target frequency is computed from the PLL multiplier and the PLL divisor. |
||||
* Use the following formula to compute your values: |
||||
* |
||||
* CORECLOCK = ((PLL_MUL + 1) * 1MHz) / PLL_DIV |
||||
* |
||||
* NOTE: The PLL circuit does not run with less than 32MHz while the maximum PLL |
||||
* frequency is 96MHz. So PLL_MULL must be between 31 and 95! |
||||
* |
||||
* |
||||
* The internal Oscillator used directly can lead to a slightly better power |
||||
* efficiency to the cost of a less stable clock. Use this option when you know |
||||
* what you are doing! The actual core frequency is adjusted as follows: |
||||
* |
||||
* CORECLOCK = 8MHz / DIV |
||||
* |
||||
* NOTE: A core clock frequency below 1MHz is not recommended |
