bypass register
The bypass register is a 1-bit scan path that can be selected to shorten the length of the system scan path,
thereby 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.

† Bit 7 is a don’t-care bit; X = don’t care.
‡ The BYPASS instruction is executed in lieu of a SCOPE

boundary scan
This instruction conforms to the IEEE Standard 1149.1-1990 EXTEST and INTEST instructions. The BSR is
selected in the scan path. Data appearing at the device input terminals is captured in the input BSCs, while data
appearing at the outputs of the normal on-chip logic is captured in the output BSCs. Data that has been scanned
into the input BSCs is applied to the inputs of the normal on-chip logic, while data that has been scanned into
the output BSCs is applied to the device output terminals. The device operates in the test mode.
