Research direction

Start by reviewing the existing PIO probe-program swapping path mentioned in the issue, then investigate how the DAP protocol represents scan-IR and scan-DR operations. Before implementation, clarify whether PIO can accelerate those operations and define the required JTAG behavior; the issue does not identify files, tests, or a completion criterion.

Written by the indexing model from the issue text.

Description

Given that we already swap probe programs in and out of PIO on the fly, it would be easy enough to add JTAG support.

How does PIO assist in this scenario - is the DAP protocol sufficiently high-level that we could accelerate scan-IR and scan-DR ops?
