Boundary Register
instruction opcode definitions. It also defines that in the Capture-IR state, the parallel inputs to the
instruction shift register are loaded with 01 in the least significant bits.
The ID code register description identifies the values captured in the device identification register when
the IDCODE instruction is executed. Example 7 shows the DSP56307 ID code register description.
The Boundary Register description lists the boundary-scan cells and gives information regarding the cell
type and associated control. Example 8 shows the DSP56307 boundary scan description. The Boundary
Register description defines the Boundary-Scan Register length as 144 bits and gives the instruction
opcode definitions
