boundary-control register
The boundary-control register (BCR) is three bits long. The BCR is used in the context of the RUNT instruction
to implement additional test operations not included in the basic SCOPE
instruction set. Such operations
include PRPG, PSA, and binary count up (COUNT). Table 4 shows the test operations that are decoded by
the BCR.
During Capture-DR, the contents of the BCR are not changed. At power up or in Test-Logic-Reset, the BCR is
reset to the binary value 010, which selects the PSA test operation. The BCR order of scan is shown in
Figure 3.

bypass register
The bypass register is a 1-bit scan path that can be selected to shorten the length of the system scan path,
reducing the number of bits per test pattern that must be applied to complete a test operation. During
Capture-DR, the bypass register captures a logic 0. The bypass register order of scan is shown in
Figure 4.
