4.3.1.3. get_hssi_profile for F-Tile

This SAL command is used to poll the DR CSR Ready for New Trigger. The DR ready for trigger status is reflected in HSSI Command/Status CSR bit 3 following the write/read CSR sequence to HSSI Command/Status CSR as shown in the following table. This get_hssi_profile SAL command is executed in HW and not through SAL NIOS firmware to avoid extra latency introduced in the DR sequence.
