(

VREF

)

Value:

(((VREF) == SDADC_VREF_Ext)      || \
                             ((VREF) == SDADC_VREF_VREFINT1) || \
                             ((VREF) == SDADC_VREF_VREFINT2) || \

#define SDADC_VREF_Ext   ((uint32_t)0x00000000)

The reference voltage is forced externally using VREF pin

#define SDADC_VREF_VDDA   SDADC_CR1_REFV

The reference voltage is forced internally to VDDA

#define SDADC_VREF_VREFINT1   SDADC_CR1_REFV_0

The reference voltage is forced internally to 1.22V VREFINT

#define SDADC_VREF_VREFINT2   SDADC_CR1_REFV_1

The reference voltage is forced internally to 1.8V VREFINT
