Detailed Description

macros to manage the specified RCC Flags and interrupts.

Macro Definition Documentation

__HAL_RCC_CLEAR_IT

#define __HAL_RCC_CLEAR_IT

(

__INTERRUPT__

)

(*(__IO uint8_t *) RCC_CIR_BYTE2_ADDRESS = (__INTERRUPT__))

Clear the RCC's interrupt pending bits.

Parameters

__INTERRUPT__

specifies the interrupt pending bit to clear. This parameter can be any combination of the following values: RCC_IT_LSIRDY LSI ready interrupt. RCC_IT_LSERDY LSE ready interrupt. RCC_IT_HSIRDY HSI ready interrupt. RCC_IT_HSERDY HSE ready interrupt. RCC_IT_PLLRDY Main PLL ready interrupt. RCC_IT_CSS Clock Security System interrupt

__HAL_RCC_CLEAR_RESET_FLAGS

#define __HAL_RCC_CLEAR_RESET_FLAGS

(

)

(*(__IO uint32_t *)RCC_CSR_RMVF_BB = ENABLE)

Set RMVF bit to clear the reset flags.

The reset flags are RCC_FLAG_PINRST, RCC_FLAG_PORRST, RCC_FLAG_SFTRST, RCC_FLAG_OBLRST, RCC_FLAG_IWDGRST, RCC_FLAG_WWDGRST, RCC_FLAG_LPWRRST

__HAL_RCC_DISABLE_IT

#define __HAL_RCC_DISABLE_IT

(

__INTERRUPT__

)

(*(__IO uint8_t *) RCC_CIR_BYTE1_ADDRESS &= (uint8_t)(~(__INTERRUPT__)))

Disable RCC interrupt.

Parameters

__INTERRUPT__

specifies the RCC interrupt sources to be disabled. This parameter can be any combination of the following values: RCC_IT_LSIRDY LSI ready interrupt RCC_IT_LSERDY LSE ready interrupt RCC_IT_HSIRDY HSI ready interrupt RCC_IT_HSERDY HSE ready interrupt RCC_IT_PLLRDY main PLL ready interrupt

__HAL_RCC_ENABLE_IT

#define __HAL_RCC_ENABLE_IT

(

__INTERRUPT__

)

(*(__IO uint8_t *) RCC_CIR_BYTE1_ADDRESS |= (__INTERRUPT__))

Enable RCC interrupt.

Parameters

__INTERRUPT__

specifies the RCC interrupt sources to be enabled. This parameter can be any combination of the following values: RCC_IT_LSIRDY LSI ready interrupt RCC_IT_LSERDY LSE ready interrupt RCC_IT_HSIRDY HSI ready interrupt RCC_IT_HSERDY HSE ready interrupt RCC_IT_PLLRDY main PLL ready interrupt

__HAL_RCC_GET_FLAG

#define __HAL_RCC_GET_FLAG

(

__FLAG__

)

Value:

                                       (((((__FLAG__) >> 5U) == CR_REG_INDEX)  ? RCC->CR   : \
                                       (((__FLAG__) >> 5U) == BDCR_REG_INDEX)? RCC->BDCR : \
                                       (((__FLAG__) >> 5U) == CFGR_REG_INDEX)? RCC->CFGR : \
                                                                              RCC->CSR) & (1U << ((__FLAG__) & RCC_FLAG_MASK)))

Check RCC flag is set or not.

Parameters

__FLAG__

specifies the flag to check. This parameter can be one of the following values: RCC_FLAG_HSIRDY HSI oscillator clock ready. RCC_FLAG_HSERDY HSE oscillator clock ready. RCC_FLAG_PLLRDY Main PLL clock ready. RCC_FLAG_LSERDY LSE oscillator clock ready. RCC_FLAG_LSIRDY LSI oscillator clock ready. RCC_FLAG_OBLRST Option Byte Load reset RCC_FLAG_PINRST Pin reset. RCC_FLAG_PORRST POR/PDR reset. RCC_FLAG_SFTRST Software reset. RCC_FLAG_IWDGRST Independent Watchdog reset. RCC_FLAG_WWDGRST Window Watchdog reset. RCC_FLAG_LPWRRST Low Power reset.

Return values

The	new state of FLAG (TRUE or FALSE).

__HAL_RCC_GET_IT

#define __HAL_RCC_GET_IT

(

__INTERRUPT__

)

((RCC->CIR & (__INTERRUPT__)) == (__INTERRUPT__))

Check the RCC's interrupt has occurred or not.

Parameters

__INTERRUPT__

specifies the RCC interrupt source to check. This parameter can be one of the following values: RCC_IT_LSIRDY LSI ready interrupt. RCC_IT_LSERDY LSE ready interrupt. RCC_IT_HSIRDY HSI ready interrupt. RCC_IT_HSERDY HSE ready interrupt. RCC_IT_PLLRDY Main PLL ready interrupt. RCC_IT_CSS Clock Security System interrupt

Return values

The	new state of INTERRUPT (TRUE or FALSE).
