Half-Duplex / Full-Duplex Select.
The ‘Pin Type’ for this pin depends on the setting for the HW/SW pin
(pin 23). When the HW/SW pin is set for:
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:
Media Independent Interface / Stream Interface (Select).
This pin is used in combination with the 10/100SEL pin to configure
the ICS1893CY-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:

Hardware mode, this pin acts as an input. In this case, when the
signal on this pin is logic:
– Low, this pin selects half-duplex operations.
– High, this pin selects full-duplex operations.
Software mode, this pin acts as an output that indicates the current
status of this pin. In this case, when the signal on this pin is logic:
– Low, this pin indicates that it is set for half-duplex operations.
– High, this pin indicates that it is set for full-duplex operations.
Low, this pin selects Hardware mode operations.
High, this pin selects Software mode operations.
Low, the ICS1893CY-10 does not have a lock on the data stream.
High, the ICS1893CY-10 has a lock on the data stream.
Low, there is no link established.
High, there is a link established.
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 in 100Base-TX or Serial Interface in 10Base-T.
Low, this pin enables the ICS1893CY-10 to default to node
operations.
High, this pin enables the ICS1893CY-10 to default to repeater
operations.
