				Forces all SRAM outputs to High-Z state. This instruction is not 1149.1-compliant.
IDCODE			001	Loads the ID register with the vendor ID code and places the register between TDI and TDO. This
				operation does not affect SRAM operations.
SAMPLE Z			010	Captures IO ring contents. Places the boundary scan register between TDI and TDO.
				Forces all SRAM output drivers to a High-Z state.
RESERVED			011	Do Not Use: This instruction is reserved for future use.
SAMPLE/PRELOAD			100	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.
RESERVED			101	Do Not Use: This instruction is reserved for future use.
