MOTOROLA FAST SRAM
STANDARD (PUBLIC) INSTRUCTION CODES
Instruction
Code*
Description
EXTEST
000
Captures I/O ring contents. Places the boundary scan register between TDI and TDO. Forces all
RAM outputs to High–Z state. *NOT 1149.1 COMPLIANT*
IDCODE
001**
Preloads ID register and places it between TDI and TDO.
Does not affect RAM operation.
SAMPLE / PRELOAD
100
Captures I/O ring contents. Places the boundary scan register between TDI and TDO. Does not
affect RAM operation.
Does not implement 1149.1 Preload function. * NOT 1149.1 COMPLIANT *
BYPASS
111
Places bypass register between TDI and TDO.
Does not affect RAM operation.
SAMPLE–Z
010
Captures I/O ring contents. Places the boundary scan register between TDI and TDO. Forces all
RAM output drivers to High–Z.
*Instruction codes expressed in binary, MSB on left, LSB on right.
**Default instruction automatically loaded at power–up and in test–logic–reset state.
