A 3-bit GPIO and 2-bit GPO (Multiplexed on the EEPROM and LED Pins) interface is included in the
LAN89218. It is accessible through the host bus interface via the CSRs. The GPIO signals can function
as inputs, push-pull outputs and open drain outputs. The GPIO’s (GPO’s are not configurable) can also
be configured to trigger interrupts with programmable polarity.
A serial EEPROM interface is included in the LAN89218. The serial EEPROM is optional and can be
programmed with the LAN89218 MAC address. The LAN89218 can optionally load the MAC address
automatically after power-on reset, hardware reset, or soft reset.
The LAN89218 supports comprehensive array of power management modes to allow use in power
sensitive applications. Wake on LAN, Link Status Change and Magic Packet detection are supported
by the LAN89218. An external PME (Power Management Event) interrupt is provided to indicate
detection of a wakeup event.
The general-purpose timer has no dedicated function within the LAN89218 and may be programmed
to issue a timed interrupt.
