7.2 Pin description
The PHY input and output pins are described in
output is defined from the perspective of the PHY. Thus a signal on a pin described as an
output is driven by the PHY and a signal on a pin described as an input is received by the
PHY. A basic description of each pin is provided.

Description
used to tell the PHY to begin a receiver
detection operation or to begin loopback;
LOW = reset state
forces TX output to electrical idle. TXIDLE
should be asserted while in power states P0s
and P1.
used when transmitting the compliance
pattern; HIGH-level sets the running disparity
to negative
signals the PHY to perform a polarity inversion
on the receive data; LOW = PHY does no
polarity inversion; HIGH = PHY does polarity
inversion
PHY reset input; active LOW
