13 * How to setup clock using clock driver functions:
14 *
15 * 1. Call CLOCK_InitXXX() to configure corresponding SCG clock source.
16 * Note: The clock could not be set when it is being used as system clock.
17 * In default out of reset, the CPU is clocked from FIRC(IRC48M),
18 * so before setting FIRC, change to use another avaliable clock source.
19 *
20 * 2. Call CLOCK_SetXtal0Freq() to set XTAL0 frequency based on board settings.
21 *
22 * 3. Call CLOCK_SetXxxModeSysClkConfig() to set SCG mode for Xxx run mode.
23 * Wait until the system clock source is changed to target source.
24 *
25 * 4. If power mode change is needed, call SMC_SetPowerModeProtection() to allow
26 * corresponding power mode and SMC_SetPowerModeXxx() to change to Xxx mode.
27 * Supported run mode and clock restrictions could be found in Reference Manual.
