2. X: Don’t care.
3. 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.
4. Negative input to SD16_A (A3−) connected to AV

if corresponding SD16AE.x bit is cleared.
5. Setting the DAC12OPS bit also disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
