Analog Front-End Pin-Level Function Multiplexing

Table 5-2 describes the relationships between the various internal signals found in the analog front-end

(AFE) and how they are multiplexed onto the external package pins. Note that, in general, only one

function is available for those pads that have numerous functions listed. The exclusion to this rule is

when a comparator is used; the ADC can still convert either input side of the comparator.
