Input or
Output
PHY (Address Bit) 2 / Link Integrity LED.
For more information on this pin, see Section 6.8, “Status Interface”.
This multi-function configuration pin is:
– An input pin during either a power-on reset or a hardware reset. In
this case, this pin configures the address of the ICS1893 when it is in
either hardware mode or software mode.
– An output pin following reset. In this case, this pin provides link status
for the ICS1893.
As an input pin:
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.
As an output pin:
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.
Caution:
This pin must not float. (See the notes at Section 9.3.2,
“Multi-Function (Multiplexed) Pins: PHY Address and LED
Pins”.)
