LED Inversion Mode
Inversion option for the LEDs for each
R/W
port [0:3]. For example, if set to 1, LED is
on when activity is not present, and off
during activity.

Notes: The following bit sequence will restore the old LED functionality: 1110100001010000.
PHY address 2 will set the LED functionality for all ports. However, the individual port’s LED functionality can be set on a PHY address by
PHY address basis. (i.e., PHY 0’s LEDs can be set to be different from PHY 1, PHY 2, and PHY 3.
