PSoC™ 4

Hi,

in the PSoC 4100S Data sheet, we can see from the pin list that VSSD is connected to ''DN'' for 40-pin QFN chips https://www.cypress.com/file/230626/download.

I cannot find any reference to DN regarding to TQFP packages, in the document or anywhere else. Does it refer to the thermal pad? There is no DN pin in the document for 32-pin QFN chips though, so I find this confusing.

Thanks!
