LAN Interrupt. When high, this signal indicates that
the LAN controller has information for iChip LAN.
Crystal Input: This pin and the X2 pin provide
connections for a fundamental mode or third-
overtone, parallel-resonant crystal used by the
internal oscillator circuit.
To provide iChip LAN with an external clock
source, connect the source to the X1 pin and leave
the X2 pin unconnected.
Crystal Output: This pin and the X1 pin provide
connections for a fundamental mode or third-
overtone, parallel-resonant crystal used by the
internal oscillator circuit.
Clock Output: This pin outputs the internal clock
and has the some frequency as X2.
Ground: iChip LAN Ground signal.
Power Supply: This pin supplies power (+5V or
+3.3V) to iChip LAN.
Must be Not Connected.
