#define __HAL_RCC_LSI_DISABLE

(

)

(*(__IO uint32_t *) RCC_CSR_LSION_BB = DISABLE)

Macro to disable the Internal Low Speed oscillator (LSI).

Note:

LSI can not be disabled if the IWDG is running.

When the LSI is stopped, LSIRDY flag goes low after 6 LSI oscillator clock cycles.

#define __HAL_RCC_LSI_ENABLE

(

)

(*(__IO uint32_t *) RCC_CSR_LSION_BB = ENABLE)

Macro to enable the Internal Low Speed oscillator (LSI).

Note:

After enabling the LSI, the application software should wait on LSIRDY flag to be set indicating that LSI clock is stable and can be used to clock the IWDG and/or the RTC.
