Note 1:
All AD1CSSH bits can be selected by user software. However, inputs selected for scan, without a
corresponding input on the device, convert V
corresponding input on the device, convert V

.
2:
The OAx input is used if the corresponding op amp is selected (OPMODE (CMxCON<10>) = 1);
otherwise, the ANx input is used.
otherwise, the ANx input is used.
