2.1. Serial Management Interface
The Serial Management Interface (SMI) allows for register configuration. The SMI bus consists of
MDIO (Data) and MDC (Clock). For the ET1011 EB, this configuration path can be directed to either
the MII Connector (P1) or to a header (J7). Two jumpers on board determine which communication
path controls the SMI bus. When communicating with the PHY on the SMI, it is necessary to configure
the PHY’s SMI address. This is accomplished using jumpers (JP4-7). The address range is from 0-15.
Refer to Table 2-1- PHY Address Selection for configuration. An auxiliary SMI header (J17) is provided
for “Daisy Chaining” multiple evaluation boards together.

2.2. Hardware Configuration
The ET1011 PHY has many hardware configuration options. For simplicity, the ET1011 EB has pre-
configured most options for easy use.
There are four configuration options that the user has access to:
J2 – Reset: Strap to enable hardware reset.
J3 – SysClk: Strap to disable SYS_CLK output
J4 – LPED: Strap to disable Low Power Energy Detect mode
J6 – Coma: Strap to enable COMA mode
