Design Considerations for
Using XDS510 Emulator
This appendix assists you in meeting the design requirements of the Texas
Instruments XDS510 emulator with respect to IEEE-1149.1 designs and
discusses the XDS510 cable (manufacturing part number 2617698-0001).
This cable is identified by a label on the cable pod marked
JTAG 3/5V and sup-
ports both standard 3-V and 5-V target system power inputs.
The term
JTAG, as used in this book, refers to TI scan-based emulation, which
is based on the IEEE 1149.1 standard.
