10BASE-T PHY Management Registers

(TBRs)

The Am79C978 home networking device supports the

MII basic register set and extended register set. Both

sets of registers are accessible through the PHY Man-

agement Interface. As specified in the IEEE standard,

the basic register set consists of the Control Register

(Register 0) and the Status Register (Register 1). The

extended register set consists of Registers 2 to 31

(decimal).

Table 64 lists all the 10BASE-T registers implemented

in the device. All the reserved registers should not be

written to, and reading them will return a zero value.
