16.5.4.15 AD_INTERFACE_REG1 Register (offset = 44h) [reset = 0h]
AD_INTERFACE_REG1 is shown in Figure 16-148 and described in Table 16-159.
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.
