INxy_BIAS

Input xy pin bias control. Controls the input pin bias configuration.

00 Open. Set if no pin bias is desired. The pin is always unbiased in this state.

01 Weakly pulled down. Set if an internal weak pulldown is desired on the input pin.

10 (Default) Weak VCM. Set if weak VCM is desired, biased to weak VCM when necessary.

7, 6 ADC1x_

PDN

ADC1x power down. Configures the ADC Channel x power state. All analog front-end circuity (preamp, PGA, etc.) associated

with that channel is powered up or down accordingly. Also enables the digital decimator associated with that channel and must

be cleared if the input channel type is digital.
