/*
|
|
* How to setup clock using clock driver functions:
|
|
*
|
|
* 1. CLOCK_SetSimSafeDivs, to make sure core clock, bus clock, flexbus clock
|
|
* and flash clock are in allowed range during clock mode switch.
|
|
*
|
|
* 2. Call CLOCK_Osc0Init to setup OSC clock, if it is used in target mode.
|
|
*
|
|
* 3. Set MCG configuration, MCG includes three parts: FLL clock, PLL clock and
|
|
* internal reference clock(MCGIRCLK). Follow the steps to setup:
|
|
*
|
|
* 1). Call CLOCK_BootToXxxMode to set MCG to target mode.
|
|
*
|
|
* 2). If target mode is FBI/BLPI/PBI mode, the MCGIRCLK has been configured
|
|
* correctly. For other modes, need to call CLOCK_SetInternalRefClkConfig
|
|
* explicitly to setup MCGIRCLK.
|
|
*
|
|
* 3). Don't need to configure FLL explicitly, because if target mode is FLL
|
|
* mode, then FLL has been configured by the function CLOCK_BootToXxxMode,
|
|
* if the target mode is not FLL mode, the FLL is disabled.
|
|
*
|
|
* 4). If target mode is PEE/PBE/PEI/PBI mode, then the related PLL has been
|
|
* setup by CLOCK_BootToXxxMode. In FBE/FBI/FEE/FBE mode, the PLL could
|
|
* be enabled independently, call CLOCK_EnablePll0 explicitly in this case.
|
|
*
|
|
* 4. Call CLOCK_SetSimConfig to set the clock configuration in SIM.
