Description
Captures the Input/Output ring contents. Places the boundary scan register be-
tween the TDI and TDO. Forces all SRAM outputs to High-Z state. This
instruction is not 1149.1 compliant.
Loads the ID register with the vendor ID code and places the register between TDI
and TDO. This operation does not affect SRAM operation.
Captures the Input/Output contents. Places the boundary scan register between
TDI and TDO. Forces all SRAM output drivers to a High-Z state.
Do Not Use: This instruction is reserved for future use.
Captures the Input/Output ring contents. Places the boundary scan register
between TDI and TDO. Does not affect the SRAM operation. This instruction does not
implement 1149.1 preload function and is therefore not 1149.1 compliant.
Do Not Use: This instruction is reserved for future use.
Do Not Use: This instruction is reserved for future use.
Places the bypass register between TDI and TDO. This operation does not
affect SRAM operation.
