AUI/TPI SELECT: A TTL level active high input that selects either the  
AUI interface or the TPI module for interface with the ENDEC module.  
When high the AUI is selected, when low the TPI is selected.

enables the ENDEC module to be tested independently of the  
DP83902A module.

CARRIER SENSE/RECEIVE: A TTL/MOS level active high signal. It is  
asserted for approximately 50 ms whenever valid transmit or receive  
data is detected while in AUI mode or receive data is detected while in  
TPI mode.
