LED INDICATORS
The LED pins use standard logic drivers. They output a logic low when the LED is meant to be on and a logic
high when it is meant to be off. The LED should be connected in series with a resistor between the output pin and
the power supply.

CO
LED LINK: ON for link up.
LEDTX
39
CO
LED TRANSMIT: ON when there is a transmission (normally OFF).
LEDRX
38
CO
LED RECEIVE: ON when there is a reception (normally OFF).
LEDCOL
37
CO
LED COLLISION: In half duplex mode, this is a collision indicator and turns ON
when a collision occurs. In full duplex mode, this LED is held OFF.
LEDBTX
36
CO
LED 100BASE-TX: ON for 100BASE-TX connection and OFF for other
connections. LEDBTX is OFF during auto-negotiation.
LEDBT
48
CO
LED 10BASE-T: ON for 10BASE-T connection and OFF for other
connections.
LEDBT
is OFF during auto-negotiation.
LEDFDX
49
CO
LED FULL DUPLEX: ON when in full duplex mode and OFF when in half
duplex mode.

CLOCK INPUT: Connects to a 25 MHz TTL compatible clock source. This
pin should be held low when XTLP and XTLN are being used as the 25 MHz
clock source.
XTLP/N
59,58
A
CRYSTAL PINS: Should be connected to a 25 MHz crystal. When CKIN is
being used as the 25 MHz clock source, these pins should be left floating or
connected together.

DESCRIPTION
INTR
35
COZ
INTERRUPT PIN: This pin is used to signal an interrupt to the media access
controller. The pin is held in the high impedance state when an interrupt is
not indicated. The pin will be forced high or low to signal an interrupt
depending upon the value of the INPOL bit (MR16.14). The events which
trigger an interrupt can be programmed via the Interrupt Control Register
located at address MR17.
