That document doesn't seem to handle the CY8C20xx7. Instead it covers Associated Part Family: CY8C21x23, CY8C21x34, CY8C21x45, CY8C22xxx, CY8C23x33, CY8C24x23A, CY8C24x94, CY8C27x43, CY8C28xxx, CY8C29x66
In any case, what analog components can be powered down then powered up without affecting capsense? I'd expected the analog block references would be reset, but what about the analog output buffers and CT/SC blocks? Also, what time delay is needed between powering them up and using them? This isn't mentioned in any of the documents I've read.
I included the doc link because the 20xx7 parts are of same basic technology.
I also cannot find answers that cover your questions, Even the TRM is very "thin" on this
