Problems using W5300

1.Sn_SSR appears as the content of 0x11, according to the description of the manual, there should not be such a state. During this state, can ping, but never link, can only be re initialized w5300.

2 Call getSn_TX_FSR, often get vaule freeSize=0. I only use a socket, and Rx/TX mem are both 64k.
If you’ve ever had a similar problem, please help me,thank you.
