Instructions for Use:

1. Power Supply Connection:

   • Connect the VCC pin to a stable 3.3V power supply.
   • Ensure proper decoupling capacitors are placed close to the VCC and GND pins.

2. Reset Configuration:

   • Apply a reset signal to the RESET pin before initializing the device.
   • Hold the reset line high for at least 1ms.

3. Interface Selection:

   • Configure the interface mode (MII/RMII) through the appropriate strapping pins during power-up.

4. Auto-Negotiation:

   • Enable auto-negotiation for automatic speed and duplex setting adjustment.
   • Monitor the status registers for completion and result of negotiation.

5. MDI/MDIX Configuration:

   • Set up MDI/MDIX mode as required using configuration bits in the control registers.

6. Signal Integrity:

   • Follow PCB layout guidelines provided in the datasheet for optimal signal integrity.
   • Keep signal traces short and direct, especially for high-speed signals.

7. Firmware Update:

   • Check for firmware updates periodically from the manufacturer's website.
   • Follow the detailed procedure for updating the firmware if necessary.

8. Testing and Validation:

   • After setup, perform thorough testing including loopback tests and compliance checks.
   • Validate performance under various operating conditions to ensure reliability.
