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. Set MCG configuration, MCG includes three parts: FLL clock, PLL clock and
21 * internal reference clock(MCGIRCLK). Follow the steps to setup:
22 *
23 * 1). Call CLOCK_BootToXxxMode to set MCG to target mode.
24 *
25 * 2). If target mode is FBI/BLPI/PBI mode, the MCGIRCLK has been configured
26 * correctly. For other modes, need to call CLOCK_SetInternalRefClkConfig
27 * explicitly to setup MCGIRCLK.
28 *
29 * 3). Don't need to configure FLL explicitly, because if target mode is FLL
30 * mode, then FLL has been configured by the function CLOCK_BootToXxxMode,
31 * if the target mode is not FLL mode, the FLL is disabled.
32 *
33 * 4). If target mode is PEE/PBE/PEI/PBI mode, then the related PLL has been
34 * setup by CLOCK_BootToXxxMode. In FBE/FBI/FEE/FBE mode, the PLL could
35 * be enabled independently, call CLOCK_EnablePll0 explicitly in this case.
36 *
37 * 4. Call CLOCK_SetSimConfig to set the clock configuration in SIM.
