The Table 6-493 shows the PRU_ICSSGn (where n = 0 to 2) MII MDIO signals and their availability at the device boundary.
MDIO Control Signals | |||
---|---|---|---|
Pin Name | Type | Available as device I/O | Function |
MDIO_LINKINT[1:0] | O | N.A. | Serial interface link change interrupt. Indicates a change in the state of the PHY link. |
MDIO_USERINT[1:0] | O | N.A. | Serial interface user command event complete interrupt. |
MDIO Interface Signals | |||
Pin Name | Type | Available as device I/O | Function |
MDIO_I | I | device bidirectioanal pr0_mdio_data, and pr1_mdio_mdclk pin in input mode | Serial data input |
MDIO_O | O | device bidirectional pr0_mdio_data and pr1_mdio_mdclk pin in output mode | Serial data output |
MDIO_OE_N | O | N.A. | Serial data output enable. Asserted "0" when data output is valid |
MDCLK_O | O | device output - pr0_mdio_mdclk pr1_mdio_mdclk | Serial clock output |
MLINK_I[1:0] | I | N.A. | Optional link status inputs from PHY. Each input is connected to a single PHY. Unused inputs are tied ‘0’. |
