__STATIC_INLINE void LL_COMP_ConfigInputs ( COMP_TypeDef *  COMPx,
uint32_t  InputInverting,
uint32_t  InputNonInverting 
)

Set COMP inputs inverting and non-inverting.

Note:
In case of comparator input selected to be connected to IO: IP pins are specific to each comparator instance. Refer to description of parameters or to reference manual.
On STM32L4, scaler bridge is configurable: to optimize power consumption, this function enables the voltage scaler bridge only when required (comparator input based on VrefInt). The scaler bridge is common for all comparator instances, therefore if at least one of the comparator instance is requiring the scaler bridge, it remains enabled. CSR INMSEL LL_COMP_ConfigInputs
