The BSCs for HSSI transmitters ( GXB_TX[p,n] ) and receivers/input clock buffers (GXB_RX[p,n]) /(REFCLK[p,n]) in Intel® Cyclone® 10 GX 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® Cyclone® 10 GX device before, after, and during configuration.
