NOTES: 1. N/A: Not available or not applicable.
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 (A2−) connected to AV_SS if corresponding SD16AE.x bit is cleared.
