IOS[2:0] Switch (SW2.2, SW2.3, SW2.4)

The IOS[2:0] bits on the USB-LAN EZ-Extender are directly connected

to the IOS[2:0] pins of the LAN91C111 Ethernet processor. These

switches, by default, are set to the OFF positions. The pins are used in con-

junction with the “Serial ROM Enable Switch (SW2.1)” to select between

predefined EEPROM configurations. For more information about the

switches, refer to the SMSC LAN91C111 data sheet.
