DP83867E: LED blink speed control consult

Part Number: DP83867E


Hi team,

My customer wants to use LED to realize below function, 

when huge data transmit in the data bus, the LED blink in a higher frequency;

when little data transmit in the data bus, the LED blink in a lower frequency;

Both event can be seen from the LED.

However customer find that the LED will be on all the time no matter how much data is transmit in the data bus.

Could you suggest some methods to realize such funtion? Thanks.

BR,

CL

  • Hi Charles,

    You can configure the LED through register write. Please use Register 0x18 in datasheet to select the source of the LED. You can choose 1011: Link established, blink for transmit or receive activity, 0011: Receive activity, 0010: Transmit activity, 0001: Receive or Transmit activity

    Thanks,

    Cecilia
