2 SWJ interconnect
The css600_swjic is a Serial Wire and JTAG interconnect that enables you to connect multiple SWJ slave components, for example Debug Ports, to a single SWJ master.
Use the css600_swjic to:
- Daisy-chain multiple JTAG Debug Ports.
- Combine the data and control signals from multiple Serial Wire Multi Drop Debug Ports.
The following figure shows the external connections on the SWJIC.

Note:
Creating long JTAG scan chains can create performance issues. Arm recommends that you avoid creating long daisy-chains if possible.
