The RJ45 Ethernet connector J44 is shown in Figure A.3.
LEDA (green) and LEDB (yellow) are connected to the LAN9118 controller. The function of the LEDs is determined by registers in the controller. Typical usage would be to monitor transmit activity and packet detection.
The signals on the Ethernet cable are listed in Table A.3.
