Cannot Set DPORT W5500

Question

I have a W5500 chip that is setup in UDP mode. And I can setup the intial transmissions that i want to occur. But sometimes i want to change the DIPR and DPORT to send to a different destination. I now have a loop that just checks that the DPORT is set properly before sending any new data. Here I have a loop that has been of setting and checking the DPORT for socket 0. The two Transactions are:I have previously verified that the chip is indeed in UDP mode and that the socket is OPEN. - 0x0010 - DPORT - 0x0E - Write two bytes to socket 0 registers. - 0x1388 - 5000 - 0x0010 - DPORT - 0x0A - Read two bytes from socket 0 registers. - 0xEB6F (NOT 5000) Is there any other conditions that are required to be met to write to these registers?

Hi. If you don’t mind sharing, could you show how you're setting DIPR and DPORT in your code? It might help narrow down the issue. Thank you.
