JTAG Data Registers
Boundary Scan Cell
Types
The C-5 NP contains the standard internal registers as specified in IEEE 1149.1. These
registers are described in
Table 29 JTAG Internal Register Descriptions
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
