tcp receive interrupt

Question

Hi, my W7500p is configured as TCP client. The TCP server will sometimes send notifications and I want to ensure that the client does not miss these notifications. I thought maybe I could poll the Socket Reveived Size register (Sn_RX_RSR). If data was received (Sn_RX_RSR >0), I would then call the socket receive function. Is this the “best” way to do it or are there other possibilities? Is there for example a possibility to trigger an interrupt when the TOE RX buffer is loaded with data?

Hi, digitig21: Is there for example a possibility to trigger an interrupt when the TOE RX buffer is loaded with data? There is no example using interrupts. But, If you use Sn_IR and Sn_IMR, it is possible. (Refer to W7500P Reference Manual p.65~)
