W5200 TCP vhdl controller

Hello,
I am attempting to implement a TCP server controller written in vhdl to control W5200 chip.
If you would tell me more about the registers behave when a client sends a SYN packet to connect, wich register is used to notify that there is a connection request.
Thnx

on page 30, you can find Sn_SR. It is socket status register and if client send SYN then receive it, Sn_SR value changed 0x14(listen) to 0x17(establish).

Thank you,
