+ *   Update CMSIS SystemCoreClock variable.
+ *
+ * @details
+ *   CMSIS defines a global variable SystemCoreClock that shall hold the
+ *   core frequency in Hz. If the core frequency is dynamically changed, the
+ *   variable must be kept updated in order to be CMSIS compliant.
+ *
+ *   Notice that only if changing the core clock frequency through the EFR CMU
+ *   API, this variable will be kept updated. This function is only provided
+ *   for CMSIS compliance and if a user modifies the the core clock outside
+ *   the CMU API.
