Macro Definition Documentation

◆ __HAL_RCC_HSI_CALIBRATIONVALUE_ADJUST

#define __HAL_RCC_HSI_CALIBRATIONVALUE_ADJUST ( _HSICALIBRATIONVALUE_ ) (MODIFY_REG(RCC->CR, RCC_CR_HSITRIM, (uint32_t)(_HSICALIBRATIONVALUE_) << RCC_CR_HSITRIM_Pos))

Macro to adjust the Internal High Speed oscillator (HSI) calibration value.

Note: The calibration is used to compensate for the variations in voltage and temperature that influence the frequency of the internal HSI RC.

Parameters

<em>HSICALIBRATIONVALUE</em> specifies the calibration trimming value. (default is RCC_HSICALIBRATION_DEFAULT). This parameter must be a number between 0 and 0x1F.

◆ __HAL_RCC_HSI_DISABLE

#define __HAL_RCC_HSI_DISABLE ( ) (*(__IO uint32_t *) RCC_CR_HSION_BB = DISABLE)

◆ __HAL_RCC_HSI_ENABLE

#define __HAL_RCC_HSI_ENABLE ( ) (*(__IO uint32_t *) RCC_CR_HSION_BB = ENABLE)

Macros to enable or disable the Internal High Speed oscillator (HSI).

Note: The HSI is stopped by hardware when entering STOP and STANDBY modes.; HSI can not be stopped if it is used as system clock source. In this case, you have to select another source of the system clock then stop the HSI.; After enabling the HSI, the application software should wait on HSIRDY flag to be set indicating that HSI clock is stable and can be used as system clock source.; When the HSI is stopped, HSIRDY flag goes low after 6 HSI oscillator clock cycles.
