is: How do you manage and use these boundary scan chains?The control of the boundary scan chain is mainly done through the TAP (Test Access Port) controller.In the next section, let's take a look at how TAP works.2-2 TAP (TEST ACCESS PORT)In the previous section, we have briefly introduced the boundary scan chain, but also understand that the general chip will provide several boundary scan chain, for the complete testing function.Below, I'll step through how to implement the control and access
