4.9 JTAG Identification (ID) Register

The JTAG ID register is a 32-bit read-only factory-programmed register that distinguishes the
component on a board according to the IEEE 1149.1 standard. Figure 4-11 shows the JTAG ID
register configuration. Version information corresponds to the revision number ($0 for revision 0,
$1 for revision A, etc.).

4.10 JTAG Boundary Scan Register (BSR)

The BSR in the DSP56311 JTAG implementation contains bits for all device signals, clock pins,
and their associated control signals. All DSP56311 bidirectional pins have a corresponding
register bit in the BSR for pin data and are controlled by an associated control bit in the BSR. For
details on the BSR, consult the DSP56300 Family Manual.
