Function name
ErrorStatus LL_RCC_DeInit (void )
Function description
Reset the RCC clock configuration to the default reset state.
Return values
An: ErrorStatus enumeration value:
SUCCESS: RCC registers are de-initialized
ERROR: not applicable
Notes
The default reset state of the clock configuration is given
below: HSI ON and used as system clock sourceHSE and
PLL OFFAHB, APB1 and APB2 prescaler set to 1.CSS, MCO

LL_RCC_GetSystemClocksFreq
Function name
void LL_RCC_GetSystemClocksFreq
(LL_RCC_ClocksTypeDef * RCC_Clocks)
Function description
Return the frequencies of different on chip clocks; System, AHB,
APB1 and APB2 buses clocks.
Parameters
RCC_Clocks: pointer to a LL_RCC_ClocksTypeDef
structure which will hold the clocks frequencies
Return values
None:
Notes
Each time SYSCLK, HCLK, PCLK1 and/or PCLK2 clock
changes, this function must be called to update structure
