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.
5. OA0I0 connected to pin if for OA0 the OAPx bits are cleared or set to 01, or if for OA1 the OAPx bits are set to 01.
