16.5.4.17 AD_INTERFACE_REG3 Register (offset = 4Ch) [reset = 0h]
AD_INTERFACE_REG3 is shown in
and described in
.
All bits (unless defined) are bypass bits for internal analog to digital interface pins with the same name. All
the bits of this register, except the over-ride bits return a '0' on read, if VDDLDO is off.
