Splet30. jan. 2024 · As we mentioned before - SWD was developed as a pseudo-replacement for JTAG. With SWD the pin count was reduced from 4 to 2 and it provides a lot of the same functionality of JTAG. One downside to SWD however is that devices can not be daisy chained together, which JTAG allowed for. The two pins that are used in SWD are below:
