After familiarizing ourselves with the JTAG architecture through a series of previous articles, let’s take a complete example to understand how the TAP used for Debug access works. Assuming a debugging scenario where we need JTAG to access and modify a 3-bit wide control signal due to debugging requirements. In normal functional mode, the value … Read more
