6.3.10 Extended Register Space Access

The DP83TD510E's SMI function supports read or write access to the extended register set using registers REGCR (0x0D) and ADDAR (0x0E) and the MDIO Manageable Device (MMD) indirect method defined in IEEE 802.3ah Draft for clause 22 for accessing the clause 45 extended register set.

The standard register set, MDIO registers 0 to 31, is accessed using the normal direct-MDIO access or the indirect method, except for register REGCR (0x0D) and ADDAR (0x0E), which is accessed only using the normal MDIO transaction. The SMI function ignores indirect accesses to these registers.

Table 6-5 REGCR DEVAD Functions
REGCR[15:14] Function
00

Accesses to register ADDAR modify the extended register ‘set address’ register. This address register must always be initialized to access any of the registers within the extended register set.
01 Accesses to register ADDAR access the register within the extended register set selected by the value in the address register.
10 Access to register ADDAR access the register within the extended register set selected by the value in the address register. After that access is complete, for both reads and writes, the value in the address register is incremented.
11 Access to register ADDAR access the register within the extended register set selected by the value in the address register. After that access is complete, for write accesses only, the value in the address register is incremented. For read accesses, the value of the address register remains unchanged.

The following sections describe how to perform operations on the extended register set using register REGCR and ADDAR. The descriptions use the device address for general MMD register accesses (DEVAD[4:0] = 11111).
