106 * Update CMSIS SystemCoreClock variable.
107 *
108 * @details
109 * CMSIS defines a global variable SystemCoreClock that shall hold the
110 * core frequency in Hz. If the core frequency is dynamically changed, the
111 * variable must be kept updated in order to be CMSIS compliant.
112 *
113 * Notice that if only changing core clock frequency through the EFM32 CMU
114 * API, this variable will be kept updated. This function is only provided
115 * for CMSIS compliance and if a user modifies the the core clock outside
116 * the CMU API.
