Description
EXTEST
IDCODE
Captures the Input/Output ring contents.
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.
