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. | ||
