(*(__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.

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.
