/**
  * @brief  Macro to calculate reload value to be set in CRS register according to target and sync frequencies
  * @note   The RELOAD value should be selected according to the ratio between the target frequency and the frequency 
  *             of the synchronization source after prescaling. It is then decreased by one in order to 
  *             reach the expected synchronization on the zero value. The formula is the following:
  *             RELOAD = (fTARGET / fSYNC) -1
  * @param  __FTARGET__ Target frequency (value in Hz)
  * @param  __FSYNC__   Synchronization signal frequency (value in Hz)
  * @retval None
