    [..]
    This subsection provides a set of functions allowing to control the RCC Clocks
    frequencies.
    [..]
    (@) Important note: Care must be taken when HAL_RCCEx_PeriphCLKConfig() is used to
        select the RTC clock source; in this case the Backup domain will be reset in
        order to modify the RTC Clock source, as consequence RTC registers (including
        the backup registers) and RCC_BDCR register are set to their reset values.

Note:: Return 0 if peripheral clock identifier not managed by this API

Parameters:

PeriphClk

Peripheral clock identifier This parameter can be one of the following values:

RCC_PERIPHCLK_I2S: I2S peripheral clock

Return values:

Frequency in KHz

HAL_StatusTypeDef HAL_RCCEx_PeriphCLKConfig ( RCC_PeriphCLKInitTypeDef * PeriphClkInit )

Initializes the RCC extended peripherals clocks according to the specified parameters in the RCC_PeriphCLKInitTypeDef.

Parameters:

PeriphClkInit pointer to an RCC_PeriphCLKInitTypeDef structure that contains the configuration information for the Extended Peripherals clocks(I2S, SAI, LTDC RTC and TIM).

Note:: Care must be taken when HAL_RCCEx_PeriphCLKConfig() is used to select the RTC clock source; in this case the Backup domain will be reset in order to modify the RTC Clock source, as consequence RTC registers (including the backup registers) and RCC_BDCR register are set to their reset values.
