JTAG/boundary-scan (IEEE Std 1149.1) is an electronic four port serialJTAG interfacethat allows access to the special embedded logic on a great many of today’s ICs (chips) . The JTAG accessible logic interface serves a number of functions that can include any or all of the following: ...
JTAG - the IEEE 1149.1 Standard JTAG/Boundary Scanor theIEEE 1149.1standard is one of the most successful electronics standards of all time and was invented to test electrical assemblies. JTAG/Boundary Scan has become an integral part of electronics development and production. ...

This section describes the JTAG-DP Instruction Register (IR), accessed through the IR scan chain. As described in B3.3.1 Required IR instructions, The width of the IR is IMPLEMENTATION DEFINED, and can be four or eight bits. So, IR length is 4-bit or ...
at solving the limited-access problems of traditional board test based on a physical-touch technology such as bed-of-nails and flying probe systems, IEEE 1149.1 boundary scan applications have expanded beyond the wildest imaginations of the original members of the Joint Test Action Group (JTAG). ...
The lock device has a hardware protection unit, which restricts access to the JTAG scanchain. In the preceding image, the SJC is a lock device. If the debugger must access the DAP, then it must unlock the lock device with a key. See the article How do I add pre-connect JTAG scans ...

Maybe one day we'd have so many users that I couldn't scan their images for them, but in the meantime there was nothing more important to do.Another thing I didn't get at the time is that growth rate is the ultimate test of a startup. Our growth rate was fine. We had about 70...
