Identification Codes

INSTRUCTION	CODE	DESCRIPTION

EXTEST	000	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.

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 I/O 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 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.

RESERVED	101	Do Not Use: This instruction is reserved for future use.

RESERVED	110	Do Not Use: This instruction is reserved for future use.

BYPASS	111	Places the bypass register between TDI and TDO. This operation does not affect
		SRAM operations.
