Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 2.7V to 5.25V.
   • Use a stable power source to avoid voltage fluctuations that can affect performance.

2. Clock Configuration:

   • The ENC28J60T-I/SS requires a 25MHz clock input. This can be provided by an external crystal or oscillator.
   • Connect the clock signal to the XIN and XOUT pins if using an external crystal.

3. Reset:

   • Apply a reset pulse to the RESET pin to initialize the device. The reset pulse should be at least 1μs long.
   • After reset, the device will enter a low-power state. Use the appropriate commands to configure and activate it.

4. SPI Communication:

   • The ENC28J60T-I/SS communicates with the host microcontroller via SPI (Serial Peripheral Interface).
   • Connect the SPI pins (SCK, MOSI, MISO, and CS) to the corresponding pins on the microcontroller.
   • Set the SPI mode to Mode 0 (CPOL = 0, CPHA = 0).

5. Configuration:

   • After reset, configure the device using the SPI interface. Common configuration settings include MAC address, IP address, and network settings.
   • Use the appropriate register write commands to set these parameters.

6. Packet Transmission:

   • To send a packet, write the packet data to the transmit buffer and then trigger the transmission using the appropriate command.
   • Monitor the status registers to ensure the packet has been transmitted successfully.

7. Packet Reception:

   • The device automatically receives packets and stores them in the receive buffer.
   • Check the status registers to determine if a packet has been received and then read the packet data from the receive buffer.
   • Clear the receive buffer after reading to make space for new packets.

8. Interrupt Handling:

   • The INT pin can be used to generate interrupts when specific events occur, such as packet reception or transmission completion.
   • Configure the interrupt enable registers to specify which events should trigger an interrupt.

9. Power Management:

   • Use the power management commands to switch between active and standby modes to conserve power when not in use.
   • Ensure that the device is properly configured before entering standby mode to avoid data loss or corruption.

10. Environmental Considerations:

    • Operate the device within the specified temperature and humidity ranges to ensure reliable performance.
    • Store the device in a dry environment to prevent damage from moisture.
