What status is W5100 Status Register Sn_SR indicating?

What status is the value 0x01 of W5100 Status Register Sn_SR indicating?
The value 0x01 of Sn_SR is not specified in anywhere of W5100 datasheet.
When I have connected W5100 with TCP client mode to TCP server, then
the status register Sn_SR of W5100 has returned the value 0x01.
What meaning is the value 0x01 of Sn_SR?
Please teach me these phenamina in detail.
