/**
* @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
