Description
EXTEST
00000000
Forces contents of the boundary scan cells onto the device outputs
(1)
.
Places the boundary scan register (BSR) between TDI and TDO.
BYPASS
11111111
Places the bypass register (BYR) between TDI and TDO.
IDCODE
00100010
Loads the ID register (IDR) with the vendor ID code and places the
register between TDI and TDO.
HIGHZ
01000100
Places the bypass register (BYR) between TDI and TDO. Forces all
device output drivers except
INT
x and
COL
x to a High-Z state.
CLAMP
00110011
Uses BYR. Forces contents of the boundary scan cells onto the device
outputs. Places the bypass register (BYR) between TDI and TDO.
SAMPLE/PRELOAD
00010001
Places the boundary scan register (BSR) between TDI and TDO.
SAMPLE allows data from device inputs
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.
