Shift-Dr, Exit1-DR, Pause-DR, Exit2-DR and Update-DR. These controller states are similar to the Shift-IR, Exit1-IR, Pause-IR, Exit2-IR and Update-IR states in the Instruction path. WebThe DR registers are similar to the IR registers (they are shifted the same way the IR registers are but using the Shift-DR state instead of the Shift-IR). Each IR value selects a different DR register. So in our example, the CPU could have up to 32 DR registers (if all IR instructions were implemented). JTAG 3 - Query the JTAG chain
