4.10JTAG Boundary Scan Register (BSR)

The BSR in the DSP56301 JTAG implementation contains bits for all device signals, clock pins, and their associated control signals. All DSP56301 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. For the latest description of the BSR contents by available package type in boundary scan description language (BSDL), call your local Motorola Semiconductor Sales Office or authorized distributor, or refer to the following Motorola website:
