HAL_RCC_GetPCLK1Freq
Function name
uint32_t HAL_RCC_GetPCLK1Freq (void )
Function description
Returns the PCLK1 frequency.
Return values
PCLK1: frequency
Notes
Each time PCLK1 changes, this function must be called to
update the right PCLK1 value. Otherwise, any configuration
based on this function will be incorrect.
HAL_RCC_GetPCLK2Freq
Function name
uint32_t HAL_RCC_GetPCLK2Freq (void )
Function description
Returns the PCLK2 frequency.
Return values
PCLK2: frequency
Notes
Each time PCLK2 changes, this function must be called to
update the right PCLK2 value. Otherwise, any configuration
based on this function will be incorrect.
