MODE[2:0]: Mode Configuration
The MODE[2:0] configuration straps control the configuration of the 10/100 digital block. When the
nRST pin is deasserted, the register bit values are loaded according to the MODE[2:0] configuration
straps. The 10/100 digital block is then configured by the register bit values. When a soft reset occurs
via the
controlled by the register bit values and the MODE[2:0] configuration straps have no affect.
The device’s mode may be configured using the hardware configuration straps as summarized in
Table
The MODE[2:0] hardware configuration pins are multiplexed with other signals as shown in
