in the unipolar-mode and bipolar-mode registers to zero to configure AIN0 and AIN1 for unipolar
single-ended conversion.
BCH2/3
Set to one to configure AIN2 and AIN3 for bipolar differential conversion. Set the corresponding bits
6
in the unipolar-mode and bipolar-mode registers to zero to configure AIN2 and AIN3 for unipolar
single-ended conversion.
BCH4/5
Set to one to configure AIN4 and AIN5 for bipolar differential conversion. Set the corresponding bits
5
in the unipolar-mode and bipolar-mode registers to zero to configure AIN4 and AIN5 for unipolar
single-ended conversion.
BCH6/7
Set to one to configure AIN6 and AIN7 for bipolar differential conversion. Set the corresponding bits
4
in the unipolar-mode and bipolar-mode registers to zero to configure AIN6 and AIN7 for unipolar
single-ended conversion.
BCH8/9
Set to one to configure AIN8 and AIN9 for bipolar differential conversion. Set the corresponding bits
3
in the unipolar-mode and bipolar-mode registers to zero to configure AIN8 and AIN9 for unipolar
single-ended conversion.
BCH10/11
Set to one to configure AIN10 and AIN11 for bipolar differential conversion. Set the corresponding
2
bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN10 and AIN11 for
unipolar single-ended conversion.
BCH12/13
Set to one to configure AIN12 and AIN13 for bipolar differential conversion. Set the corresponding
1
bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN12 and AIN13 for
unipolar single-ended conversion.
BCH14/15
0 (LSB)
Set to one to configure AIN14 and AIN15 for bipolar differential conversion. Set the corresponding
bits in the unipolar-mode and bipolar-mode registers to zero to configure AIN14 and AIN15 for
unipolar single-ended conversion.
