Field Descriptions
Bit | Field | Value | Description |
Reserved | 0 | Reserved | |
LINKINTRAW |
| MDIO Link change event, raw value. When asserted, a bit indicates that there was an MDIO link | |
|
|
| change event (that is, change in the LINK register) corresponding to the PHY address in |
|
|
| USERPHYSEL. LINKINTRAW[0] and LINKINTRAW[1] correspond to USERPHYSEL0 and |
|
|
| USERPHYSEL1, respectively. Writing a 1 will clear the event and writing a 0 has no effect. |
|
| 0 | No MDIO link change event. |
|
| 1 | An MDIO link change event (change in the LINK register) corresponding to the PHY address in |
|
|
| MDIO user PHY select register n (USERPHYSELn). |
