Table 7. Bipolar-Mode Register (Addressed Through the Setup Register)

BIT NAME

BIT

FUNCTION

BCH0/1

7 (MSB)

Set to one to configure AIN0 and AIN1 for bipolar differential conversion. Set the corresponding bits

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

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

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

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

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

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

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.
