Low level JTAG commands allow you to scan multiple FPGA JTAG chains. The SVF commands generated for chain operations use these low-level commands to access the FPGAs in the chain.

This appendix is an overview of these commands. A detailed explanation can be found in the Serial Vector Format Specification document that can be found at: http://www.jtagtest.com/pdf/svf_specification.pdf.
