__STATIC_INLINE void LL_RCC_HSI_Disable

(

void

)

Disable HSI oscillator.

Reference Manual to LL API cross reference:

CR HSION LL_RCC_HSI_Disable

None

Definition at line 2999 of file stm32f4xx_ll_rcc.h.

__STATIC_INLINE void LL_RCC_HSI_Enable

(

void

)

Enable HSI oscillator.

Reference Manual to LL API cross reference:

CR HSION LL_RCC_HSI_Enable

Return values:

None

__STATIC_INLINE uint32_t LL_RCC_HSI_GetCalibration

(

void

)

Get HSI Calibration value.

Note:

When HSITRIM is written, HSICAL is updated with the sum of HSITRIM and the factory trim value

Return values:

Between

Min_Data = 0x00 and Max_Data = 0xFF

Definition at line 3021 of file stm32f4xx_ll_rcc.h.

__STATIC_INLINE uint32_t LL_RCC_HSI_GetCalibTrimming

(

void

)

Get HSI Calibration trimming.

Reference Manual to LL API cross reference:

CR HSITRIM LL_RCC_HSI_GetCalibTrimming

Return values:

Between

Min_Data = 0 and Max_Data = 31

Definition at line 3045 of file stm32f4xx_ll_rcc.h.

__STATIC_INLINE uint32_t LL_RCC_HSI_IsReady

(

void

)

Check if HSI clock is ready.

Reference Manual to LL API cross reference:

CR HSIRDY LL_RCC_HSI_IsReady

Return values:

State

of bit (1 or 0).

Definition at line 3009 of file stm32f4xx_ll_rcc.h.

__STATIC_INLINE void LL_RCC_HSI_SetCalibTrimming

(

uint32_t

Value

)

Set HSI Calibration trimming.

Note:

user-programmable trimming value that is added to the HSICAL

Default value is 16, which, when added to the HSICAL value, should trim the HSI to 16 MHz +/- 1 %

Reference Manual to LL API cross reference:

CR HSITRIM LL_RCC_HSI_SetCalibTrimming

Parameters:

Value

Between Min_Data = 0 and Max_Data = 31

Return values:

None
