Tool/software:

The Pin K16 in the datasheet of afe5832 is NC, but the reference design is SPI_DIG_EN. This question bothers me. Can you give me some advice? Thanks.

Hi.

Pin K16 is used in AFE58JD32 device . Since reference design is made compatible for both afe5832 and afe58JD32 you see them as not NC.

Thank you.

I have another question to consult. Does the odd VCA register have no way to read and write anymore if we used AFE5832 in the pcb and PIN K15 is NC? Thanks.

No, You should be able to read and write.

As shown in the figure, K15 is SENo in the AFE5832 datasheet. Is this datasheet wrong?

Hi,

Sorry, I got confused between K15 and K16 pin . Datasheet description is correct .

This AFE uses 2 VCA dies internally . 16 channel is from each VCA die . SENo controls all the odd channel in the AFE . So if you make K15 NC you cannot control the register writes corresponding to odd channels .
