Description
Captures I/O ring contents. Places the boundary scan register between TDI
and TDO. Forces all device outputs to High-Z state. This instruction is not
IEEE 1149.1-compliant.
Preloads ID register with vendor ID code and places it between TDI and
TDO. This instruction does not affect device operations.
Captures I/O ring contents. Places the boundary scan register between TDI
and TDO. Forces all device outputs to High-Z state.
Do not use these instructions; they are reserved for future use.
Captures I/O ring contents. Places the boundary scan register between TDI
and TDO. This instruction does not affect device operations. This instruction
does not implement IEEE 1149.1 PRELOAD function and is therefore not
1149.1-compliant.
Do not use these instructions; they are reserved for future use.
Do not use these instructions; they are reserved for future use.
Places the bypass register between TDI and TDO. This instruction does not
affect device operations.
