2.16.3. TX 2-Step Timestamp Interface

A separate TX 2-step timestamp interface is available for each supported port within a reconfiguration group.

For 400GE rate, width of TX 2-step timestamp is 2x of other Ethernet rates. The interface signals of port 2 and port 0 are concatenated for 400GE port 0 usage as below: 
{msb, lsb} == {<i/o>_p2_ptp_<signals>, <i/o>_p0_ptp_<signals>}
The below table shows the interface details for different numbers of ports.
