My First Day. Sacred Heart Hospital was a private teaching hospital in San DiFrangeles, California. It offered emergency services, clinical help, and other medical processes. It had a large staff of surgical and medical doctors, and offered a great educational setting for medical students and interns.
The Joint Test Action Group (JTAG) is an electronics industry association formed in 1985 for developing a method of verifying designs and testing printed circuit boards after manufacture.
The JTAG pins are usually dedicated (not shared for other purposes). All big ICs use boundary testing using JTAG - boundary testing is the original reason JTAG was created. But wouldn't it be nice to use JTAG for more purposes than just boundary testing? CPU and FPGA manufacturers allow JTAG to be used as debug port.
