__STATIC_INLINE void LL_COMP_ConfigInputs	(	COMP_TypeDef *	COMPx,
		uint32_t	InputMinus,
		uint32_t	InputPlus
	)

Set comparator inputs minus (inverting) and plus (non-inverting).

Note:

In case of comparator input selected to be connected to IO: GPIO pins are specific to each comparator instance. Refer to description of parameters or to reference manual.

On this STM32 series, scaler bridge is configurable: to optimize power consumption, this function enables the voltage scaler bridge only when required (when selecting comparator input based on VrefInt: VrefInt or subdivision of VrefInt).

For scaler bridge power consumption values, refer to device datasheet, parameter "IDDA(SCALER)".
Voltage scaler requires a delay for voltage stabilization. Refer to device datasheet, parameter "tSTART_SCALER".
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.
