The 10/100 Ethernet MAC function is implemented in the AT91CAP9 EMAC module.
This module manages an RMII 10/100 Base-T Fast-Ethernet PHY Auto-MDIX (SMSC LAN8700) to
implement a 10/100 Base-T Ethernet port.
The implementation is shown below.
R86
The 1.8V core power supply is external by default, to minimize 3.3V power consumption.
Use of LAN8700 3.3V/1.8V internal regulator can be done by disconnected J36 and R71 REG_OFF Pull-
up.
