Description

 

 

 

 

 

 

 

 

 

 

 

EXTEST

 

000

Captures the IO 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 operations.

 

 

 

SAMPLE Z

 

010

Captures the 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 the IO ring contents. Places the boundary scan register between TDI and TDO.

 

 

 

 

 

 

Does not affect SRAM operation.

 

 

 

 

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.
