and TDO. This operation does not affect SRAM operations.
Captures I/O ring contents. Places the boundary scan register between TDI and TDO.
Forces all SRAM output drivers to a High-Z state.
Does not affect SRAM operation. This instruction does not implement 1149.1 preload
function and is therefore not 1149.1-compliant.
Places the bypass register between TDI and TDO. This operation does not affect
SRAM operations.
