AD5941 AFEx connection


I am designing a hardware with AD5941.

We have some confusion about the connections of AFEx. Figure 3 suggests that the AFEx inputs are not connected to the MUX. Instead, where the AD5940 (Figure 2) shows AFEx, there is only AINx.

Referring to Table 7 and the pin descriptions AFEx input are simply referred to as 'Uncommitted Analog Pin' while AINx include "This pin connects to the switch matrix" - This would further suggest that the AFEx pins are not connected to the switch matrix

Cross referencing with Figure 36 & 37 would suggest the AFEx - MUX connections are the same for AD5940 and 5941 and AFEx is indeed connected to the switch matrix.

Can someone at ADI confirm the connections of AFEx inputs?
