2.2.2.2 Example 2 – Level Change Mode Indication on RX_D3 with Secure-ON (DP83822)

MAC ADDRESS = 00:17:83:DD:23:79

Secure-ON Password = DF-CB-85-68-17-05

To enable Magic Packet detection with Secure-ON using level change indication on RX_D3 use the following register writes:

Note: MAC IF must be in RMII operation since RX_D3 is used in MII and RGMII operation.
