JTAG (Joint Test Action Group) is an international standard testing protocol (IEEE 1149.1) primarily used for testing, debugging, and programming chips, PCBs, and systems. Through a dedicated hardware interface and protocol, it provides non-intrusive access to the internal circuits of chips. The JTAG protocol is widely used in embedded development, hardware verification, and fault diagnosis. … Read more
