(1) X = Don't care
(2) N/A = Not available or not applicable
(3) Default after reset (PUC/POR)
(4) Setting the SD16AE.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals.
(5) In JTAG mode the internal pullup/down resistors are disabled.
(6) With SD16AE.x = 0 the negative inputs are connected to VSS if the corresponding input is selected.
(7) Function controlled by JTAG
