Captures I/O ring contents. Places the boundary scan register between TDI and TDO.
Forces all SRAM outputs to High-Z state. This instruction is not 1149.1-compliant.
Loads the ID register with the vendor ID code and places the register between TDI and
TDO. This operation does not affect SRAM operations.
Captures I/O ring contents. Places the boundary scan register between TDI and TDO.
Forces all SRAM output drivers to a High-Z state.
Do Not Use: This instruction is reserved for future use.
Captures I/O ring contents. Places the boundary scan register between TDI and TDO.
Does not affect SRAM operation. This instruction does not implement 1149.1 preload
function and is therefore not 1149.1-compliant.
Do Not Use: This instruction is reserved for future use.
Do Not Use: This instruction is reserved for future use.
Places the bypass register between TDI and TDO. This operation does not affect SRAM
operations.
