The DP83867 supports connection to an Ethernet MAC via the following interfaces: RGMII, GMII, and MII.
The RGMII Disable strap (RX_D6) determines the default state of the MAC interface. The RGMII Disable strap corresponds to the RGMII Enable (bit 7) in the RGMIICTL register (address 0x0032). When RGMII mode is disabled, the DP83867 operates in GMII mode.
| RGMII ENABLE (Register 0x0032, bit 7) | DEVICE FUNCTIONAL MODE |
|---|---|
| 0x1 | RGMII |
| 0x0 | GMII |
The initial strap value for the RGMII disable is also available in the Strap Configuration Status Register 1 (STRAP_STS1).
