the EthernetENC library (and I guess the lwIP_enc28j60 too) does a software reset at initialization. wiring reset pins together does a hardware reset of the enc28j60 when the MCU is reset with the reset pin or watchdog. |

Hello, in all the images/tutorials/examples I see on the web, in addition to the 4 SPI pins, there is connection of the RST and INT pins to ESP 4 and 5. I don't see any reference at those pins in the source code, with a scope I see no activity on the pins, I can disconnect them and the sketch works fine.
At this point, I would like a confirmation there are no side-effects connecting those pins to something else (very useful indeed!). In any case, I think that a note on the pins would be useful in the readme file.
