Array A
Forces contents of the boundary scan cells onto the device outputs
Places the boundary scan register (BSR) between TDI and TDO.
Places the bypass register (BYR) between TDI and TDO.
Loads the ID register (IDR) with the vendor ID code and places the
register between TDI and TDO.
Places the bypass register (BYR) between TDI and TDO. Forces all
device output drivers except INTx and COLx to a High-Z state.
Uses BYR. Forces contents of the boundary scan cells onto the device
outputs. Places the bypass register (BYR) between TDI and TDO.
Places the boundary scan register (BSR) between TDI and TDO.
SAMPLE allows data from device inputs
boundary scan cells and shifted serially through TDO. PRELOAD allows
data to be input serially into the boundary scan cells via the TDI.
Several combinations are reserved. Do not use codes other than those
identified above.
For internal use only.
