(1) The external reference voltage is selected by: SREF2 = 0, SREF1 = 0, SREF0 = 1. dVREF = V_R+ - V_R-.

(2) Parameters are derived using the histogram method.

(3) Parameters are derived using a best fit curve.

(4) The gain error and the total unadjusted error are dominated by the accuracy of the integrated reference module absolute accuracy. In this mode the reference voltage used by the ADC12_A is not available on a pin.
