* @brief | |
* 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 if only changing core clock frequency through the EFM32 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. | |
