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 ICS1893CF. 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 ICS1893CF does not have
– Asserted, this state indicates the ICS1893CF has activity.

When the signal on this pin is:
– De-asserted, this state indicates the ICS1893CF does not detect any
– Asserted, this state indicates the ICS1893CF detects collisions.
The ICS1893CF asserts its Collision LED for a period of approximately
70 msec when it detects a collision.
