/*
* How to setup clock using clock driver functions:
*
* 1. Call CLOCK_InitXXXPLL() to configure corresponding PLL clock.
*
* 2. Call CLOCK_InitXXXpfd() to configure corresponding PLL pfd clock.
*
* 3. Call CLOCK_SetMux() to configure corresponding clock source for target clock out.
*
* 4. Call CLOCK_SetDiv() to configure corresponding clock divider for target clock out.
*
* 5. Call CLOCK_SetXtalFreq() to set XTAL frequency based on board settings.
