Summary

Declaration

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

Argument

Description

__HSICalibrationValue__

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

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