1) TUE is tested at V_AREF = V_DDP + 0.1 V, V_AGND = 0 V. It is verified by design for all other voltages within the
defined voltage range.
If the analog reference supply voltage drops below 4.5 V (i.e. V_AREF ≥ 4.0 V) or exceeds the power supply
voltage by up to 0.2 V (i.e. V_AREF = V_DDP + 0.2 V) the maximum TUE is increased to ±3 LSB. This range is not
subject to production test.
The specified TUE is guaranteed only, if the absolute sum of input overload currents on Port 5 pins (see I_OV
specification) does not exceed 10 mA, and if V_AREF and V_AGND remain stable during the respective period of
time. During the reset calibration sequence the maximum TUE may be ±4 LSB.
