Integrity Testing is disabled, polarity detection is based only on received data. Polarity correction is
always enabled.

Collision Detection Function
The collision detection function operates on the twisted- pair side of the interface. For standard
(half-duplex) 10BASE-T operation, a collision is defined as the simultaneous presence of valid
signals on both the TPI circuit and the TPO circuit. The LXT901A/907A Transceiver reports
collisions to the back-end via the COL pin. If the TPI circuit becomes active while there is activity
on the TPO circuit, the TPI data is passed to the back-end over the RXD circuit, disabling normal
loopback. Figure 6 on page 16 is a state diagram of the LXT901A/907A Transceiver collision
detection function. Refer to Test Specifications for collision detection and COL/CI output timing.
Note:
For full-duplex operation on the TP or AUI port, the collision detection circuitry must be disabled
by setting FDE Low.
