specification, while the remaining registers provide
enhanced monitoring and control capabilities.
As many as 31 devices may share a single Manage-
ment Interface. A unique five-bit PHY address is
associated with each device, with all devices re-
sponding to PHY address 00000. The CS8952 de-
termines its PHY address at power-up or reset
through the PHYAD[4:0] pins.

MII Management Frame Structure
Frames transmitted through the MII Management
Interface have the following format (Table 6):
When the management interface is idle, the MDIO
signal will be tri-stated, and the MAC is required to
keep MDIO pulled to a logic ONE.
At the beginning of each transaction, the MAC will
typically send a sequence of 32 contiguous logic
ONE bits on MDIO with 32 corresponding clock
cycles on MDC to provide the CS8952 with a pat-
tern that it can use to establish synchronization.
Optionally, the CS8952 may be configured to oper-
ate without the preamble through bit 9 of the PCS
Sub-Layer Configuration Register (address 17h).
The Start of Frame is indicated by a 01 bit pattern.
