indicator.
Caution:
during reset. This inversion provides a signal that can illuminate an LED during an asserted state. For
example, if a multi-function configuration pin is pulled down to ground through an LED and a
current-limiting resistor, then the sampled sense of the input is low. To illuminate an LED for the
asserted state requires the output to be high.
Each of these pins monitor the data link by providing signals that directly drive LEDs.

This multi-function configuration pin is:
– An input pin during either a power-on reset or a hardware reset. In
– An output pin following reset. In this case, this pin provides indication
This pin establishes the address for the ICS1893AF. When the signal
on this pin is logic:
– Low, that address bit is set to logic zero.
– High, that address bit is set to logic one.
When the signal on this pin is:
– De-asserted, this state indicates the ICS1893AF does not have
– Asserted, this state indicates the ICS1893AF has activity.
this case, this pin configures the ICS1893AF PHY address Bit 0.
