Description
Captures the Input/Output ring contents. Places the boundary scan register between 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.
