◆ __HAL_RCC_LSEDRIVE_CONFIG

#define __HAL_RCC_LSEDRIVE_CONFIG (   __RCC_LSEDRIVE__)    (MODIFY_REG(RCC->BDCR, RCC_BDCR_LSEDRV, (uint32_t)(__RCC_LSEDRIVE__) ))

Macro to configures the External Low Speed oscillator (LSE) drive capability.

Note
As the LSE is in the Backup domain and write access is denied to this domain after reset, you have to enable write access using HAL_PWR_EnableBkUpAccess() function before to configure the LSE (to be done once after reset).
Parameters
<strong>RCC_LSEDRIVE</strong>specifies the new state of the LSE drive capability. This parameter can be one of the following values:
  • RCC_LSEDRIVE_LOW: LSE oscillator low drive capability.
  • RCC_LSEDRIVE_MEDIUMLOW: LSE oscillator medium low drive capability.
  • RCC_LSEDRIVE_MEDIUMHIGH: LSE oscillator medium high drive capability.
  • RCC_LSEDRIVE_HIGH: LSE oscillator high drive capability.
Return values
None
