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
DQ pins to High–Z state.
NOT IEEE 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 IEEE 1149.1 PRELOAD function.
NOT IEEE 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
DQ pins to High–Z state.
*Instruction codes expressed in binary; MSB on left, LSB on right.
**Default instruction automatically loaded at power up and in test–logic–reset state.
