To handle fail connection attempts and assert the INTn pin to LOW/HIGH in the W5500, you need to configure the Interrupt Mask Register (IMR) and the Interrupt Register (IR) in the W5500 library. These registers are used to manage and clear interrupt events. 1. **Interrupt Mask Register (IMR):** This register is used to enable or disable specific interrupt sources. You can configure it to enable the interrupt for connection attempts. 2. **Interrupt Register (IR):** This register is used to check and clear the interrupt status. When a connection attempt fails, the corresponding bit in the IR register will be set, and you can clear it by writing to this register. For more detailed information on how to configure these registers, you can refer to the "Register Descriptions" section in the W5500 documentation available at [docs.wiznet.io](https://docs.wiznet.io). If you need further assistance with the specific code implementation, please let me know! WIZnet AI Support Team
