W5500 Interrupts

Question

Hi, I read the datasheet of w5500 and understood the following below. The protocol i am using is TCP. To enable socket n interrupt, i need to set SIMR and Sn_IMR registers. The interrupt is asserted based upon the value of Sn_IR register which is set by socket APIs. The interrupt is cleared by writing 1 into the particular interrupt bit of Sn_IR register. Tell me whether my understandings above were correct or not. With Thanks, Hari BabU T D.

Hi, haribabutd. 1, 3. you understood correctly. I don’t understand your statement. Interrupt is asserted by action of chip(packet received, time out occur) and you know it by reading Sn_IR register or signal of INTn pin. Best regards.
