Autodetecting Serial Wire Debug

Serial Wire Debug (SWD) does not support a scan chain in the same way that JTAG does. When autoconfiguring in SWD mode, the debug hardware unit:

  1. Adds the ARMCS-DP device to the scan chain configuration.

  2. Optionally reads the CoreSight ROM Table to add the remaining devices. This is done by default, but you can override this.
