7.3.4 EEE for Legacy MACs not Supporting 802.3az

The DP83C8201Fx is configurable to initiate LPI signaling (Idle and Refresh) through register programming as well. This feature enables the system to perform EEE even when the MAC used is not supporting EEE. In this mode, responsibility of enabling and disabling LPI signaling lies on the Host Controller Application. While the DP83C8201Fx is in LPI signaling mode, the application moves the DP83C8201Fx into the active mode before sending any data over the MAC interface.

The DP83C8201Fx does not have the buffering capability to store the data while in LPI signaling mode. To enable EEE through register configuration, the following registers must be configured:

  1. Enable EEE capabilities by writing 0x04D1.0 = 1, 0x04D1.3 = 1
  2. Advertise EEE capabilities during auto-negotiation by writing (MMD7 0x203C.1 = 1)
  3. Renegotiate the link by writing 0x0000.9 = 1
  4. Forced Tx LPI idles by writing 0x04D1.12 = 1
  5. Write 0x04D1.12 = 0 to stop transmitting LPI Idles
