HAL_StatusTypeDef HAL_RCC_DeInit

(

void

)

Resets the RCC clock configuration to the default reset state.

Note:

The default reset state of the clock configuration is given below:

• HSI ON and used as system clock source
• HSE, PLL, PLLI2S and PLLSAI OFF
• AHB, APB1 and APB2 prescaler set to 1.
• CSS, MCO1 and MCO2 OFF
• All interrupts disabled

This function doesn't modify the configuration of the

• Peripheral clocks
• LSI, LSE and RTC clocks

Return values:

HAL

void HAL_RCC_GetOscConfig

(

RCC_OscInitTypeDef *

RCC_OscInitStruct

)

Configures the RCC_OscInitStruct according to the internal RCC configuration registers.

Parameters:

RCC_OscInitStruct

pointer to an RCC_OscInitTypeDef structure that will be configured.

Note:

This function is only available in case of STM32F410xx/STM32F446xx/STM32F469xx/STM32F479xx/STM32F412Zx/STM32F412Vx/STM32F412Rx/STM32F412Cx devices.

This function add the PLL/PLLR factor management

Return values:

None

HAL_StatusTypeDef HAL_RCC_OscConfig

(

RCC_OscInitTypeDef *

RCC_OscInitStruct

)

Initializes the RCC Oscillators according to the specified parameters in the RCC_OscInitTypeDef.

Parameters:

RCC_OscInitStruct

pointer to an RCC_OscInitTypeDef structure that contains the configuration information for the RCC Oscillators.

Note:

The PLL is not disabled when used as system clock.

Transitions LSE Bypass to LSE On and LSE On to LSE Bypass are not supported by this API. User should request a transition to LSE Off first and then LSE On or LSE Bypass.

Transition HSE Bypass to HSE On and HSE On to HSE Bypass are not supported by this API. User should request a transition to HSE Off first and then HSE On or HSE Bypass.

This function add the PLL/PLLR factor management during PLL configuration this feature is only available in STM32F410xx/STM32F446xx/STM32F469xx/STM32F479xx/STM32F412Zx/STM32F412Vx/STM32F412Rx/STM32F412Cx devices
