MDIO RA 6—Auto-Negotiation (AN) Expansion Register
Figure 4-6 shows the format for the auto-negotiation (AN) expansion register, MDIO RA 6, in the
MC92604. All bits of register 6 are read-only and the register contains data received from the link partner.
4.2.7
MDIO RA 7–14—Not Supported
MDIO RA 7–14 registers, as shown in Table 4-1, are not supported in the MC92604 PHY.
4.2.8
MDIO RA 15—Extended Status Register
Figure 4-7 shows the content of the extended status register, MDIO RA 15, and its state for the MC92604.
The register is read-only and may not be modified. The MC92604 only supports 1000BASE-X, full-duplex
operation. Therefore, bit 15 is forced to a one and bits 14–12 are forced to zeros.
