1) TUE is tested at V
AREF = 5.0 V, VAGND = 0 V, VDD = 4.9 V. It is guaranteed by design for all other voltages
within the defined voltage range.
If the analog reference supply voltage exceeds the power supply voltage by up to 0.2 V
(i.e.
VAREF = VDD = +0.2 V) the maximum TUE is increased to ±3/11 LSB. This range is not 100% tested.
The specified TUE is guaranteed only if the absolute sum of input overload currents on Port 5 pins and P1H
pins (see
IOV specification) does not exceed 10 mA.
During the reset calibration sequence the maximum TUE may be
±4 LSB (±12 LSB for channels 16 … 23).

result register with the conversion result.

This parameter depends on the ADC control logic. It is not a real maximum value, but rather a fixum.
