Description
Captures Input/Output ring contents. Places the boundary scan register between TDI and
TDO. Forces all SRAM outputs to High-Z state.
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 Input/Output 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.
