The #MK64FN1M0VMD12 on-board ADC is configurable to use either (VREFH and VREFL)or (VALTH and VALTL) as the voltage reference, via the ADCx_SC2.REFSEL register bits. While VREFH and VREFL are available as dedicated pins, I cannot find what pins are connected when (VALTH and VALTL) are selected as the voltage reference.
The Reference Manual states the following:
But VALTH and VALTL are never mentioned in the datasheet. Does selection of the "alternate voltage reference" simply use VDDA and VSSA?
Hi
Here the chip configuration information refers to section 3.7.1.6 ADC Reference Options
