Table 7-3 : 21143 Configuration EEPROM Content
7.3 21143 Ports
The 21143 MII port connects to an Intel LXT970 Fast Ethernet transceiver to build the Fast Ethernet
interface available at the RJ45 connector on the front plate.
The 21143 AUI port connects to the VME P2 connector.
The 21143 10Base-T TP port is not used.
7.4 21143 GEP Pin Usage
The 21143 GEP[0] pin is used as an output that connects to the LXT970 Fast Ethernet transceiver
reset input.
A low on the GEP[0] output holds the LXT970 in reset. The LXT970 is also reset by a PCI reset.
The 21143 GEP[3:1] pins are used as inputs.
Interrupts for GEP[1:0] inputs must be disabled.
7.5 Media Capabilities
10/100Base-TX Ethernet interface on the RJ45 front panel connector.
AUI port for a 10Base-T or 10Base2 Ethernet interface on the VME P2 Connector.
