LED Display (PHY) Pins
The LED pins use standard logic drivers. They output a logic low when the LED is meant to be on and
are tri-state when it is meant to be off. The LED cathode should be connected to the output pin and a
series resistor from the power supply connected to the LED anode.

PHY display LED0 (Link OK)
The default for LED0 is Link OK (LED is on for link established).
LED1
92
OZ
PHY display LED1 (Activity)
The default for LED1 is Link Activity (LED blinks for Rx or Tx data
transferred).

PROM_CS
75
O
EEPROM Chip Select
Used to frame transmissions to and from an external
EEPROM.
PROM_CLK

O
EEPROM Clock
Clock for transmitting to and from an external EEPROM/ROM.
This is compatible with the slowest commercial parts, which
specify a maximum frequency of 1 MHz.
PROM_DI
77
I
EEPROM Data In
Data line for transmitting from the external EEPROM to the
controller. Must be high with no EEPROM present.
PROM_DO
76
OZ
EEPROM Data Out
Transfers data from the controller to an external
EEPROM/ROM.
