| 1:0 | LINKINTRAW | R/W | 0h | MDIO link change event raw value. Normal mode operation: When asserted '1', a bit indicates that there was an MDIO link change event (i.e. change in the MDIOLink register) corresponding to the PHY address in the MDIOUserPhySel register. [0]LINKINTRAW and [1]LINKINTRAW correspond to MDIOUserPhySel0 and MDIOUserPhysel1, respectively. Writing a 1h will clear the event and writing 0h has no effect. If the [17] INT_TEST_ENABLE bit in the CPSW_MDIO_CONTROL_REG register is set, the host may set LINKINTRAW bits to a 1h which may be used for test purposes. MDIO link change event raw value. State Change Mode operation: The [0]LINKINTRAW bit will be asserted '1' when any bit (for any PHY) in the MDIOAlive or MDIOLink registers changes due to MDIO operations. The [1]LINKINTRAW bit is unused in State Change Mode. State Change Mode allows any state change in any PHY to issue an interrupt. If the [17] INT_TEST_ENABLE bit in the CPSW_MDIO_CONTROL_REG register is set, the host may set the [0]LINKINTRAW bit to a 1h which may be used for test purposes. |
