◆ __HAL_RCC_LSI_DISABLE

#define __HAL_RCC_LSI_DISABLE ( ) (*(__IO uint32_t *) RCC_CSR_LSION_BB = DISABLE)

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)

Macros to enable or disable 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.; 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.; 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.
