Hardware Control Interface
Configuration options and operational settings of the device include such variables as link
establishment, MAC interface operation and control, and physical address of the device. Individual
chip addressing allows multiple LXT1000 devices to share the GMII in either mode.
all hardware selectable configurations. Some configuration bits are read only at hardware reset.
For hardware-only applications, the Hardware Control Interface provides continuous control of the
LXT1000. This mode is selected by driving the MDDIS input High.
In this setting, read and write operations on the MDIO interface are disabled; use is solely
monitoring applications.
For software or MAC-managed applications, the Hardware Control Interface provides initial
settings of the MII Register bits. This mode is selected by driving MDDIS Low.
