Function Documentation

void HAL_RCCEx_DisableLSECSS

(

void

)

Disables the LSE Clock Security System.

Note:

LSE Clock Security System can only be disabled after a LSE failure detection.

Return values:

None

Definition at line 3016 of file stm32h7xx_hal_rcc_ex.c.

References __HAL_RCC_DISABLE_IT, and RCC_IT_LSECSS.

void HAL_RCCEx_EnableLSECSS

(

void

)

Enables the LSE Clock Security System.

Note:

Prior to enable the LSE Clock Security System, LSE oscillator is to be enabled with HAL_RCC_OscConfig() and the LSE oscillator clock is to be selected as RTC clock with HAL_RCCEx_PeriphCLKConfig().

Return values:

None

Definition at line 3006 of file stm32h7xx_hal_rcc_ex.c.

void HAL_RCCEx_EnableLSECSS_IT

(

void

)

Enable the LSE Clock Security System Interrupt & corresponding EXTI line.

Note:

LSE Clock Security System Interrupt is mapped on EXTI line 18

Return values:

None

Definition at line 3028 of file stm32h7xx_hal_rcc_ex.c.

void HAL_RCCEx_KerWakeUpStopCLKConfig

(

uint32_t

WakeUpClk

)

Configure the oscillator Kernel clock source for wakeup from Stop.

Parameters:

WakeUpClk,:

Kernel Wakeup clock This parameter can be one of the following values: RCC_STOP_KERWAKEUPCLOCK_CSI: CSI oscillator selection RCC_STOP_KERWAKEUPCLOCK_HSI: HSI oscillator selection

Return values:

None

void HAL_RCCEx_LSECSS_Callback

(

void

)

RCCEx LSE Clock Security System interrupt callback.

Return values:

none

Definition at line 3736 of file stm32h7xx_hal_rcc_ex.c.

Referenced by HAL_RCCEx_LSECSS_IRQHandler().

void HAL_RCCEx_LSECSS_IRQHandler

(

void

)

Handle the RCC LSE Clock Security System interrupt request.

Return values:

None

Definition at line 3717 of file stm32h7xx_hal_rcc_ex.c.

References __HAL_RCC_CLEAR_IT, __HAL_RCC_GET_IT, HAL_RCCEx_LSECSS_Callback(), and RCC_IT_LSECSS.

void HAL_RCCEx_WakeUpStopCLKConfig

(

uint32_t

WakeUpClk

)

Configure the oscillator clock source for wakeup from Stop and CSS backup clock.

Parameters:

WakeUpClk,:

Wakeup clock This parameter can be one of the following values: RCC_STOP_WAKEUPCLOCK_CSI: CSI oscillator selection RCC_STOP_WAKEUPCLOCK_HSI: HSI oscillator selection

Note:

This function shall not be called after the Clock Security System on HSE has been enabled.

Return values:

None

Definition at line 3055 of file stm32h7xx_hal_rcc_ex.c.

References __HAL_RCC_WAKEUPSTOP_CLK_CONFIG, assert_param, and IS_RCC_STOP_WAKEUPCLOCK.

void HAL_RCCEx_WWDGxSysResetConfig

(

uint32_t

RCC_WWDGx

)

Configure WWDG1 to generate a system reset not only CPU reset(default) when a time-out occurs.

Parameters:

RCC_WWDGx,:

WWDGx to be configured This parameter can be one of the following values: RCC_WWDG1: WWDG1 generates system reset

Note:

This bit can be set by software but is cleared by hardware during a system reset

Return values:

None
