If an overload condition occurs on maximum 2 not selected analog input pins and the absolute sum of input
overload currents on all analog input pins does not exceed 10 mA, an additional conversion error of 1/2 LSB
is permissible.
resistance of the reference source must allow the capacitance to reach their final voltage level within the
indicated time. The maximum internal resistance results from the programmed conversion timing.
