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 link status
This pins establishes the address for the ICS1893. 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 ICS1893 does not have a link.
– Asserted, this state indicates the ICS1893 has a valid link.
