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. | ||
