Instruction Codes
Instruction		Code			Description
EXTEST		000	Captures the Input/Output ring contents.
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 operation.

			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 the Input/Output ring contents. Places the boundary scan register
			between TDI and TDO. Does not affect the SRAM operation.
