The Solution

IEEE Std 1149.1 -JTAG Boundary Scan Standard

This allows pin level access to BS compliant devices independent of the packaging technology via a 4 wire serial interface.

Benefits of IEEE1532Allows configuring, programming, read back,

verify, erase of programmable devices after it has been assembled on the PCB.

Allows concurrent programming which improve significantly the time it cost to program a board with several programming devices.

Eliminate the need to have multiple vendor programming tools to program their respective devices.
