I am using a Wiznet812MJ module with dsPIC33FJ128GP802 and i have written my own routines to write and read from wiznet registers.
I have reached far enough so that I can send a ping request from a computer and get a response back from the wiznet module.
Now I'm trying to create sockets but I am having problems. I am writing some data to wiznet's DHAR, DIPR and DPORT registers and when I read them back, I get only default values of those registers instead of the values I wrote. But if I write the same value to RMSR, TMSR or GAR registers then I can read them back later fine.
Does anyone know why these particular registers are being reset to defaults? Is it supposed to do that? I went through the datasheets and driver code written for AVR and followed similar steps in my program. Maybe I am missing something here?
Here's wiznet's datasheet:

Thanks.
