2.5.11. GTS Transceivers do not support direct EXTEST JTAG instruction in boundary scan test

Description

Due to an issue with the Boundary Scan Circuitry of GTS Transceivers, the EXTEST JTAG instruction can not be executed directly.

Workaround

Intel recommends using the EXTEST_PULSE/EXTEST_TRAIN JTAG instruction on GTS transceivers. In cases where the EXTEST JTAG instruction is still mandatory, you can perform it by executing the SAMPLE/PRELOAD JTAG instruction ahead of each EXTEST JTAG instruction.
