13 * How to setup clock using clock driver functions:
14 *
15 * 1. call CLOCK_SetSimSafeDivs() to set the system clock dividers in SIM to safe value.
16 *
17 * 2. If external oscillator is used Call CLOCK_SetXtal0Freq() to set XTAL0 frequency based on board settings and
18 * call CLOCK_InitOsc0() to init the OSC.
19 *
20 * 3. Call CLOCK_BootToXxxMode()/CLOCK_SetXxxMode() to set ICS run at the target mode.
21 *
22 * 4. If ICSIRCLK is needed, call CLOCK_SetInternalRefClkConfig() to enable the clock.
23 *
24 * 5. call CLOCK_SetSimConfig() to configure the divider in sim.
