Hardware/Software (Select).
When the signal on this pin is logic:
(Stream Cipher) Lock (Acquired).
When the signal on this pin is logic:
Link Status.
This pin is used to report the status of the link segment. When the
signal on this pin is logic:
This pin is mapped according to the interface for which the
ICS1893Y-10 is mapped. For the:
Media Independent Interface / Stream Interface (Select).
This pin is used in combination with the 10/LP and 10/100SEL pins to
configure the ICS1893Y-10 MAC/Repeater Interface. When the signal
on this pin is logic:
Node/Repeater (Select).
This selection on this pin affects both the SQE test and the Carrier
Sense (CSR) signal. When the signal on this pin is logic:
(Frequency) Reference Input.
This pin is connected to a 25-MHz oscillator or crystal. For a tolerance,
see
(Frequency) Reference Output.
This pin is used with a crystal.

Low, this pin selects Hardware mode operations.
High, this pin selects Software mode operations.
Low, the ICS1893Y-10 does not have a lock on the data stream.
High, the ICS1893Y-10 has a lock on the data stream.
Low, there is no link established.
High, there is a link established.
Media Independent Interface (MII), the LSTA is mapped as LSTA.
100M Symbol Interface, the LSTA is mapped as SD.
10M Serial Interface, the LSTA is mapped as LSTA.
Link Pulse Interface, the LSTA is mapped as SD.
Low, this pin configures the MAC/Repeater Interface as a Media
Independent Interface.
High, this pin configures the MAC/Repeater Interface as a Stream
Interface.
Low, this pin enables the ICS1893Y-10 to default to node
operations.
High, this pin enables the ICS1893Y-10 to default to repeater
operations.
When the signal on this active-low pin is logic:
– Low, the ICS1893Y-10 is in hardware reset.
– High, the ICS1893Y-10 is operational.
