My question is related to Serial Wire Debug protocol.
1. SWD protocol : In the document (CoreSight components trm): ARM DDI 0314H, page 2-20,Fig 2-10, how RD[1] came to DAP bus before it could come at AHB bus? Can you please explain the read timing diagram in detail.
2. To do a SWD read, do we need to send read request twice, as the first read data is discarded?
Can anyone please reply to my query ?
