3 / 29 page Architecture Figure 1 shows the basic architecture of the ’STA111. The device’s major functional blocks are illustrated here. The TAP Controller, a 16-state state machine, is the central con- trol for the device. The instruction register and various test data registers can be scanned to exercise the various func- tions of the ’STA111 (these registers behave as defined in IEEE Std. 1149.1). The ’STA111 selection controller provides the functionality that allows the 1149.1 protocol to be used in a multi-drop environment. It primarily compares the address input to the slot identification and enables the ’STA111 for subsequent scan operations. The Local Scan Port Network (LSPN) contains multiplexing logic used to select different port configurations. The LSPN control block contains the Local Scan Port Controllers (LSPC) for each Local Scan Port (LSP 0, LSP1 ... LSPn). This control block receives input from the ’STA111 instruction register, mode registers, and the TAP controller. Each local port contains all four boundary scan signals needed to interface with the local TAPs plus the optional Test Reset signal (TRST). 10124503 FIGURE 1.
