CLEAR_BIT
CLEAR_BIT(hrtc->Instance->CR, RTC_CR_WUTE)

◆ LL_OPAMP_Enable()

__STATIC_INLINE void LL_OPAMP_Enable ( OPAMP_TypeDef *  OPAMPx)

Enable OPAMP instance.

Note
After enable from off state, OPAMP requires a delay to fullfill wake up time specification. Refer to device datasheet, parameter "tWAKEUP". CSR OPAMPXEN LL_OPAMP_Enable
Parameters
OPAMPxOPAMP instance
Return values
None
