WebBoundary-scan, as defined by the IEEE Std.-1149.1 standard, is an integrated method for testing interconnects on printed circuit boards (PCBs) that are implemented at the integrated circuit (IC) level. The inability to … WebA TAP controller is a 16-state machine, programmed by the Test Mode Select (TMS) and Test Clock (TCK) inputs, which controls the flow of data bits to the Instruction Register (IR) and the Data Registers (DR). The TAP Controller can be thought of as the control center of a boundary-scan device. The TAP Controller State Diagram shown in Figure 1 ...
