The Serial Management Interface is the KS8993F non-standard MIIM interface that provides access to all KS8993F
configuration registers. This interface allows an external device to completely monitor and control the states of the
KS8993F.
The SMI interface consists of the following:
A physical connection that incorporates the data line (MDIO) and the clock line (MDC).
A specific protocol that operates across the aforementioned physical connection that allows an external
controller to communicate with the KS8993F device.
Access to all KS8993F configuration registers. Registers access includes the Global, Port and Advanced
Control Registers 0-127 (0x00 – 0x7F), and indirect access to the standard MIIM registers [0:5].
The following table depicts the Serial Management Interface frame format.

For the KS8993F, SMI register access is selected when bit 2 of the PHY address is set to ‘1’. PHY address bits [1:0]
are not defined for SMI register access, and hence can be set to either 0’s or 1’s in read/write operation.
To access the KS8993F registers 0-127 (0x00 – 0x7F), the following applies:
PHYAD[4:3] and REGAD[4:0] are concatenated to form the 7-bits address.
i.e., {PHYAD[4:3], REGAD[4:0]} = bits [6:0] of the 7-bits address.
Registers are 8 data bits wide. For read operation, data bits [15:8] are read back as 0’s. For write
operation, data bits [15:8] are not defined, and hence can be set to either 0’s or 1’s.
SMI register access is the same as the MIIM register access, except for the register access requirements presented in
this section.
