LED/ADDRESS Circuit

The following pins of the VSC8201 are input/output pins:

• ADDR(4)/ACTIVITY

• ADDR(3)/DUPLEX

• ADDR(2)/LINK1000

• ADDR(1)/LINK100

• ADDR(0)/LINK10

• REG_EN/QUALITY

In input mode these pins are sampled on the rising edge of RST# signal. After reset these are in output mode.The ADDR and REG_EN

pins sampled at startup determine the polarity of the LED output signal.

The QUALITY LED is asserted when the signal quality is good.
