O
LED display for 100M b/s or 10M b/s speed. Active low indicates
100Base-TX, active high indicates 10 BaseT.
LED display for link and activity status. Active low when link is
established.
LED display for Full Duplex or Collision status. Active low
indicates full duplex, high indicates collision in half duplex.
Note:
The LED interface is EEPROM-programmable, 2 bit EEPROM control bit, Address 0B[7:6] at EEPROM,
is used to select LED mode, the default setting are:
(1) LED0: 100Mbps(on, drive ‘0’) or 10Mbps(off, drive ‘1’)
(2) LED1: link (keeps on when link ok) or activity (blink with 10Hz when Pegasus II is receiving or
transmitting but not collision)
(3) LED2: full duplex (keeps on when in full duplex mode) or collision (blink with 20Hz when
colliding)
(4) All LED pins will be tri-state when using external PHY (offset 81h with bit[4:2] = 3’b001)
Mapping between LED action and EEPROM 0B[7:6] setting:
EEPROM 0B [7:6]

This enables the EEPROM during loading of the Ethernet
configuration data.
CMOS I/O with 5V tolerant, 2mA
EEPROM Data In

O
The MAC will use this pin to serially write opcodes, addresses
and data into the serial EEPROM.
CMOS I/O with 5V tolerant, 2mA
EEPROM Data Out, internal pull low
EEDO
5
I
EESK
3
O
The MAC will read the contents of the EEPROM serially through
this pin.
Input, pull down, 5V tolerant
EEPROM Clock
After reset, the MAC if configured, will read the contents of the
EEPROM using EESK, EEDO, and EEDI. This pin provides the clock
for the EEPROM.
CMOS I/O with 5V tolerant, 2mA
Miscellaneous
These pins are used as general purpose Input/Output pins and
GPIO[5:0]
9,8,24,26,27,28 I/O
offset 0A[1] = 0 in EEPROM.
Default is internal pull-low
POREN#

Internal Power On Reset Logic Enable.
Default is enable and internal pull - low.
When external hardware reset is used, this pin should be
connected to Vcc via 4.7k resistor.
