Serial Wire Debug (SWD) Protocol: Efficient Debug Interface For Arm-Based Systems


Modern embedded systems are becoming increasingly compact, power efficient, and feature rich. As SoCs integrate more functionality, developers need reliable debug access without increasing pin count or board complexity. Serial Wire Debug (SWD) addresses these needs by providing a streamlined alternative to JTAG, enabling high performance debug features using only two pins, making it ideal for t... » read more
