117 * @details
118 * CMSIS defines a global variable SystemCoreClock that shall hold the
119 * core frequency in Hz. If the core frequency is dynamically changed, the
120 * variable must be kept updated in order to be CMSIS compliant.
121 *
122 * Notice that if only changing core clock frequency through the EFM32 CMU
123 * API, this variable will be kept updated. This function is only provided
124 * for CMSIS compliance and if a user modifies the the core clock outside
125 * the CMU API.
