System Interface Parameters
Instruction Code 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.
