SMSC LAN8700/LAN8700I
DATASHEET
In this mode, during transmission (TX_EN is HIGH), nothing is transmitted to the line and the
transmitters are powered down.
5.4.9
Configuration Signals
The PHY has 11 configuration signals whose inputs should be driven continuously, either by external
logic or external pull-up/pull-down resistors.
5.4.9.1
Physical Address Bus - PHYAD[4:0]
The PHYAD[4:0] signals are driven high or low to give each PHY a unique address. This address is
latched into an internal register at end of hardware reset. In a multi-PHY application (such as a
repeater), the controller is able to manage each PHY via the unique address. Each PHY checks each
management data frame for a matching address in the relevant bits. When a match is recognized, the
PHY responds to that particular frame. The PHY address is also used to seed the scrambler. In a multi-
PHY application, this ensures that the scramblers are out of synchronization and disperses the
electromagnetic radiation across the frequency spectrum.
5.4.9.2
Mode Bus – MODE[2:0]
The MODE[2:0] bus controls the configuration of the 10/100 digital block.
