I have a question regarding SPL Packet Synchronization
Reference 1 - In Spl4Rev08, in Packet Mode Train Rx SNW (Speed Negotiation Window), page no. 231, it indicates
If the PHY's receiver:
a) Achieves SPL packet synchronization within the TLT, then, after completing transmission of the current PACKET_SYNC_LOST, the PHY shall change from transmitting PACKET_SYNC_LOSTs to transmitting PACKET_SYNCs for the remainder of the Train_Rx-SNW window time (i.e., the remainder of the SNW time); or
b) Does not achieve SPL packet synchronization within the TLT, then the phy shall continue transmitting PACKET_SYNC_LOSTs for the remainder of the MRTT (i.e., the remainder of the SNW time).
Reference 2 - In Spl4Rev08, Section - 18.104.22.168
>From the SP Phy Layer state machine, Start PS message(which starts SPL Packet Synchronization state machine) is enabled after Phy_Ready.
Which SPL packet synchronization is the specification talking about in Train-Rx SNW ?
