JTAG Data Registers

The C-5 NP contains the standard internal registers as specified in IEEE 1149.1. These

registers are described in Table 31.

Boundary Scan Cell Types

The C-5 NP boundary scan register contains only two cell types. All input cells are observe

only cells of type BC_4. All enable and output cells are standard cells of type BC_1. In IEEE

1149.1-1990 specification, the BC_4 cell is shown in Figure 7 and the BC_1 cell is shown in

Figure 8.
