1) _{Suffix x = 0 refers to ADC0 and suffix x = 1 refers to ADC1.}
2) _{The value of VAREF is permitted to be within the range of VSSA - 0.05 V < VAREF < VDDM + 0.05 V. The value}
specified for the total unadjusted error (TUE) is not guaranteed while the V_AREF is out of the specified range.
3) _{The value of VAGND is permitted to be within the range of VSSA - 0.05 V < VAGND < VDDM + 0.05 V. The value}
specified for the total unadjusted error (TUE) is not guaranteed while the V_AGND is out of the specified range.
4) _{Definitions for CPS, STC, tBC and tDIV see Figure 23.}
5) _{TUE is tested at VAREF = 5 V, VAGND = 0 V and VDDM = 4.9 V.}
6) _{Analog overload conditions during operation occur if the voltage on the respective ADC pin exceeds the}
specified operating range (i.e. V_AOV > V_DDM + 0.5 V or V_AOV < V_SSM - 0.5 V) or a short circuit condition occurs
on the respective ADC pin. The absolute sum of input currents on all port pins must not exceed 10 mA at any
time. The supply voltage (V_DD, V_DDA0, V_DDA1 and V_SS, V_SSA0, V_SSA1) must remain within the specified limits.
Under short-circuit conditions the corresponding pin is not ready for use.
7) _{Applies for one analog input pin.}
8) _{Applies for two numeric adjacent analog input pins.}
