4.10 JTAG Boundary Scan Register (BSR)
The boundary scan register (BSR) in the DSP56364 JTAG implementation contains bits for all device
signal and clock pins and associated control signals. All bidirectional pins have a single register bit in the
boundary scan register for pin data, and are controlled by an associated control bit in the boundary scan
register. The boundary scan register bit definitions are described in Table 4 -6 The BSDL file may be found
in Appendix B, "BDSL File".
