I'm planing to use the K22 MCU and according to the datasheet, the 16bit accuracy can be achieved only on the differential pin.
My question is if I can use the pins of the differential ADC as single ended ADC measured relatively to VSSA and in 16bit accuracy?
BTW, what is the resolution of the other ADC pins? according to the datasheet, there's a few options. It is programmable and up to 12bit?
