7.5. LED and PHY Address Configuration
In order to reduce the pin count on the RTL8201CP, the LED pins are duplexed with the PHY address
pins. Because the PHYAD strap options share the LED output pins, the external combinations required
for strapping and LED usage must be considered in order to avoid contention. Specifically, when the LED
outputs are used to drive LEDs directly, the active state of each output driver is dependent on the logic
level sampled by the corresponding PHYAD input upon power-up/reset. For example, as Figure 5 (left-
side) shows, if a given PHYAD input is resistively pulled high then the corresponding output will be
configured as an active low driver. On the right side, we can see that if a given PHYAD input is
resistively pulled low then the corresponding output will be configured as an active high driver. The PHY
address configuration pins should not be connected to GND or VCC directly, but must be pulled high or
low through a resistor (ex 5.1K
). If no LED indications are needed, the components of the LED path
(LED+510
) can be removed.
