3.3. Control and Status Signals

The PR HSSI Interface provides signals for HSSI PHY PCS status and transceiver loopback control. The signal behavior conforms to the Intel® Stratix® 10 FPGA Transceiver Native PHY IP core in 32-bit PCS-Direct mode. The below table cross references the HSSI port names to the Native PHY IP port names.
