To calculate TX and RX datapath delay:
- Convert the latency values to 16-bit nanoseconds and 16-bit fractional nanoseconds by multiplying the values by 216 or 65536.
- Write the calculated 16-bit values to the TX and RX latency registers of the Low Latency Ethernet 10G MAC:
- Write the lower 16-bit TX values to 0x10A register (TX fns value).
- Write the upper 16-bit TX values to 0x10C register (TX ns value).
- Write the lower 16-bit RX values to 0x12A register (RX fns value).
- Write the upper 16-bit RX values to 0x12C register (RX ns value).
