MDIO Addressing
The protocol allows one controller to communicate between two LXT972A chips. Pin ADDR0 is
set high or low to determine the chip address.
MDIO Frame Structure
The physical interface consists of a data line (MDIO) and clock line (MDC). The frame structure is
shown in Figure 3 and Figure 4 (read and write). MDIO Interface timing is shown in Table 34 on
3.2.3.2
MII Interrupts
The LXT972A provides a single interrupt pin (MDINT). Interrupt logic is shown in Figure 5. The
LXT972A also provides two dedicated interrupt registers. Register 18 provides interrupt enable
and mask functions and Register 19 provides interrupt status. Setting bit 18.1 = 1, enables the
device to request interrupt via the MDINT pin. An active Low on this pin indicates a status change
on the LXT972A. Interrupts may be caused by four conditions:
Auto-negotiation complete
Speed status change
Duplex status change
Link status change
3.2.3.3
Hardware Control Interface
The LXT972A provides a Hardware Control Interface for applications where the MDIO is not
desired. The Hardware Control Interface uses the three LED driver pins to set device configuration.
