<> 144:ef7eb2e8f9f7 9 * This file provides two functions and one global variable to be called from

<> 144:ef7eb2e8f9f7 14 *
<> 144:ef7eb2e8f9f7 15 * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
<> 144:ef7eb2e8f9f7 16 * by the user application to setup the SysTick
<> 144:ef7eb2e8f9f7 17 * timer or configure other parameters.
<> 144:ef7eb2e8f9f7 18 *
<> 144:ef7eb2e8f9f7 19 * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
