LAN_RSTSYNC
I
LAN I/F Clock: This signal is driven by the LAN Connect component. The
frequency range is 5 MHz to 50 MHz.
Received Data: The LAN Connect component uses these signals to transfer data
I and control information to the integrated LAN controller. These signals have
integrated weak pull-up resistors.
O
Transmit Data: The integrated LAN controller uses these signals to transfer data
and control information to the LAN Connect component.
O
LAN Reset/Sync: The LAN Connect component’s Reset and Sync signals are
multiplexed onto this pin.
