CLAMP
determined by the contents of the boundary-scan register and selects the one-
bit bypass register to be connected between TDI and TDO. Before loading this
instruction, the contents of the boundary-scan register can be preset with the
SAMPLE/PRELOAD instruction. During this instruction, data can be shifted
through the bypass register from TDI to TDO without affecting the condition of
the outputs.
HIGH-IMPEDANCE

and selects the one-bit bypass register to be connected between TDI and TDO.
During this instruction, data can be shifted through the bypass register from TDI
to TDO without affecting the condition of the device outputs.
BYPASS
functional mode and selects the one-bit bypass register to be connected
between TDI and TDO. The BYPASS instruction allows serial data to be
transferred through the IC from TDI to TDO without affecting the operation of
the device.
The required BYPASS instruction allows the device to remain in a normal
