When the user is working with Kinetis® devices, PEmicro's Cyclone MAX JTAG/SWD Adpater converts the Cyclone MAX's standard 20-pin connector to mini-10 and mini-20 connectors and allows for the selection of either JTAG or SWD communications. It includes both mini-20 and mini-10 pin ribbon cables.
Serial Wire Debug (SWD) allows debug with 2 pins, instead of the 5 that are used with JTAG. This is ideal when working with MCUs with fewer pins.
