 * 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.
