Detailed Description

macros to manage the specified RCC Flags and interrupts.

Macro Definition Documentation

__HAL_RCC_ENABLE_IT

#define __HAL_RCC_ENABLE_IT

(

__INTERRUPT__

)

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

Enable RCC interrupt (Perform Byte access to RCC_CIR[14:8] bits to enable the selected interrupts).

Parameters

<strong>INTERRUPT</strong>

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. RCC_IT_PLLI2SRDY: PLLI2S ready interrupt.

__HAL_RCC_DISABLE_IT

#define __HAL_RCC_DISABLE_IT

(

__INTERRUPT__

)

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

Disable RCC interrupt (Perform Byte access to RCC_CIR[14:8] bits to disable the selected interrupts).

Parameters

<strong>INTERRUPT</strong>

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. RCC_IT_PLLI2SRDY: PLLI2S ready interrupt.

__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 (Perform Byte access to RCC_CIR[23:16] bits to clear the selected interrupt pending bits.

Parameters

<strong>INTERRUPT</strong>

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_PLLI2SRDY: PLLI2S ready interrupt. RCC_IT_CSS: Clock Security System interrupt

__HAL_RCC_GET_IT

#define __HAL_RCC_GET_IT

(

__INTERRUPT__

)

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

Check the RCC's interrupt has occurred or not.

Parameters

<strong>INTERRUPT</strong>

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_PLLI2SRDY: PLLI2S ready interrupt. RCC_IT_CSS: Clock Security System interrupt

Return values

The	new state of INTERRUPT (TRUE or FALSE).

__HAL_RCC_CLEAR_RESET_FLAGS

#define __HAL_RCC_CLEAR_RESET_FLAGS

(

)

(RCC->CSR |= RCC_CSR_RMVF)

Set RMVF bit to clear the reset flags: RCC_FLAG_PINRST, RCC_FLAG_PORRST, RCC_FLAG_SFTRST, RCC_FLAG_IWDGRST, RCC_FLAG_WWDGRST and RCC_FLAG_LPWRRST.

RCC_FLAG_MASK

#define RCC_FLAG_MASK   ((uint8_t)0x1FU)

Check RCC flag is set or not.

Parameters

<strong>FLAG</strong>

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_PLLI2SRDY: PLLI2S clock ready. RCC_FLAG_LSERDY: LSE oscillator clock ready. RCC_FLAG_LSIRDY: LSI oscillator clock ready. RCC_FLAG_BORRST: POR/PDR or BOR 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).
