† Bit 7 is used to maintain even parity in the 8-bit instruction.
‡ The BYPASS instruction is executed in lieu of a SCOPE
™ instruction that is not supported in the ’ABT8543.
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 pins 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 pins. The device operates in the test mode.
bypass scan
This instruction conforms to the IEEE Standard 1149.1-1990 BYPASS instruction. The bypass register is
selected in the scan path. A logic 0 value is captured in the bypass register during Capture-DR. The device
operates in the normal mode.
sample boundary
This instruction conforms to the IEEE Standard 1149.1-1990 SAMPLE/PRELOAD instruction. The BSR is
selected in the scan path. Data appearing at the device input pins is captured in the input BSCs, while data
appearing at the outputs of the normal on-chip logic is captured in the output BSCs. The device operates in the
normal mode.
