Captures IO 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 IO 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 IO 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.
