Detailed Description
Macro Definition Documentation
◆ __HAL_RCC_LSI_DISABLE
| #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.
◆ __HAL_RCC_LSI_ENABLE
| #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.
