2.4. IEEE Std. 1149.6 Boundary-Scan Register

The BSCs for high-speed serial interface (HSSI) transmitters ( TX[p,n] ) and receivers/input clock buffers (RX[p,n]) /(REFCLK[p,n]) in Intel® Agilex™ devices are different from the BSCs for the I/O pins.

Note: You have to use the EXTEST_PULSE JTAG instruction for AC-coupling on HSSI transceiver. Do not use the EXTEST JTAG instruction for AC-coupling on HSSI transceiver. You can perform AC JTAG on the Intel® Agilex™ device before, after, and during configuration.
