Macro Definition Documentation

__HAL_RCC_CLEAR_IT

#define __HAL_RCC_CLEAR_IT

(

This parameter can be any combination of the following values: RCC_IT_LSIRDY: LSI ready interrupt RCC_IT_LSERDY: LSE ready interrupt RCC_IT_CSIRDY: CSI ready interrupt RCC_IT_HSIRDY: HSI ready interrupt RCC_IT_HSERDY: HSE ready interrupt RCC_IT_HSI48RDY: HSI48 ready interrupt RCC_IT_PLLRDY: main PLL ready interrupt RCC_IT_PLL2RDY: PLL2 ready interrupt RCC_IT_PLL3RDY: PLL3 ready interrupt RCC_IT_HSECSS: HSE Clock Security interrupt RCC_IT_LSECSS: Clock security system interrupt

__HAL_RCC_DISABLE_IT

#define __HAL_RCC_DISABLE_IT

(

__INTERRUPT__

)

CLEAR_BIT(RCC->CIER, (__INTERRUPT__))

__HAL_RCC_ENABLE_IT

#define __HAL_RCC_ENABLE_IT

(

__INTERRUPT__

)

SET_BIT(RCC->CIER, (__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_CSIRDY: HSI ready interrupt RCC_IT_HSIRDY: HSI ready interrupt RCC_IT_HSERDY: HSE ready interrupt RCC_IT_HSI48RDY: HSI48 ready interrupt RCC_IT_PLLRDY: main PLL ready interrupt RCC_IT_PLL2RDY: PLL2 ready interrupt RCC_IT_PLL3RDY: PLL3 ready interrupt RCC_IT_LSECSS: Clock security system interrupt

__HAL_RCC_GET_FLAG

#define __HAL_RCC_GET_FLAG

(

__FLAG__

)

Value:

(((((((__FLAG__) >> 5U) == 1U)? RCC->CR :((((__FLAG__) >> 5U) == 2U) ? RCC->BDCR : \
((((__FLAG__) >> 5U) == 3U)? RCC->CSR : ((((__FLAG__) >> 5U) == 4U)? RCC->RSR :RCC->CIFR))))  & (1UL << ((__FLAG__) & RCC_FLAG_MASK)))!= 0U)? 1U : 0U)

__HAL_RCC_GET_IT

#define __HAL_RCC_GET_IT

(

__INTERRUPT__

)

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

Check the RCC's interrupt has occurred or not.

Parameters

__INTERRUPT__

specifies the RCC interrupt source to check. This parameter can be any combination of the following values: RCC_IT_LSIRDY: LSI ready interrupt RCC_IT_LSERDY: LSE ready interrupt RCC_IT_CSIRDY: CSI ready interrupt RCC_IT_HSIRDY: HSI ready interrupt RCC_IT_HSERDY: HSE ready interrupt RCC_IT_HSI48RDY: HSI48 ready interrupt RCC_IT_PLLRDY: main PLL ready interrupt RCC_IT_PLL2RDY: PLL2 ready interrupt RCC_IT_PLL3RDY: PLL3 ready interrupt RCC_IT_HSECSS: HSE Clock Security interrupt RCC_IT_LSECSS: Clock security system interrupt

Return values

The	new state of INTERRUPT (TRUE or FALSE).

RCC_FLAG_MASK

#define RCC_FLAG_MASK   ((uint8_t)0x1F)
