Description
EXTEST
0000
Forces contents of the boundary scan cells onto the device outputs(1).
Places the boundary scan register (BSR) between TDI and TDO.
BYPASS
1111
Places the bypass register (BYR) between TDI and TDO.
IDCODE
0010
Loads the ID register (IDR) with the vendor ID code and places the
register between TDI and TDO.
HIGHZ
0100
Places the bypass register (BYR) between TDI and TDO. Forces all
device output drivers to a High-Z state.
CLAMP
0011
Uses BYR. Forces contents of the boundary scan cells onto the device
outputs. Places the bypass register (BYR) between TDI and TDO.
SAMPLE/PRELOAD
0001
Places the boundary scan register (BSR) between TDI and TDO.
SAMPLE allows data from device inputs(2) and outputs(1) to be captured
in the boundary scan cells and shifted serially through TDO. PRELOAD
allows data to be input serially into the boundary scan cells via the TDI.
RESERVED
All other codes
Several combinations are reserved. Do not use codes other than those
identified above.
