Overview of SCANPSC110F Bridge Functions

FIGURE 2. SCANPSC110F Bridge State Machines
The SCANPSC110F contains three distinct but coupled
state-machines (see Figure 2). The first of these is the
TAP-control state-machine, which is used to drive the
SCANPSC110Fs scan ports in conformance with the
1149.1 Standard (see Figure 17 of appendix). The second
is the SCANPSC110F-selection state-machine (Figure 3).
The third state-machine actually consists of three identical
but independent state-machines (see Figure 4), one per
SCANPSC110F local scan port. Each of these scan port-
selection state-machines allows individual local ports to be
inserted into and removed from the SCANPSC110Fs over-
all scan chain.
The SCANPSC110F selection state-machine performs the
address matching which gives the SCANPSC110F its
multi-drop
