13 * How to setup clock using clock driver functions:
14 *
15 * 1. CLOCK_SetSimSafeDivs, to make sure core clock, bus clock, flexbus clock
16 * and flash clock are in allowed range during clock mode switch.
17 *
18 * 2. Call CLOCK_Osc0Init to setup OSC clock, if it is used in target mode.
19 *
20 * 3. Call CLOCK_SetMcgliteConfig to set MCG_Lite configuration.
21 *
22 * 4. Call CLOCK_SetSimConfig to set the clock configuration in SIM.
