10 * How to setup clock using clock driver functions:
11 *
12 * 1. CLOCK_SetSimSafeDivs, to make sure core clock, bus clock, flexbus clock
13 * and flash clock are in allowed range during clock mode switch.
14 *
15 * 2. Call CLOCK_Osc0Init to setup OSC clock, if it is used in target mode.
16 *
17 * 3. Set MCG configuration, MCG includes three parts: FLL clock, PLL clock and
18 * internal reference clock(MCGIRCLK). Follow the steps to setup:
19 *
20 * 1). Call CLOCK_BootToXxxMode to set MCG to target mode.
21 *
22 * 2). If target mode is FBI/BLPI/PBI mode, the MCGIRCLK has been configured
23 * correctly. For other modes, need to call CLOCK_SetInternalRefClkConfig
24 * explicitly to setup MCGIRCLK.
25 *
26 * 3). Don't need to configure FLL explicitly, because if target mode is FLL
27 * mode, then FLL has been configured by the function CLOCK_BootToXxxMode,
28 * if the target mode is not FLL mode, the FLL is disabled.
29 *
30 * 4). If target mode is PEE/PBE/PEI/PBI mode, then the related PLL has been
31 * setup by CLOCK_BootToXxxMode. In FBE/FBI/FEE/FBE mode, the PLL could
32 * be enabled independently, call CLOCK_EnablePll0 explicitly in this case.
33 *
34 * 4. Call CLOCK_SetSimConfig to set the clock configuration in SIM.
