No Connect.
This pin is always reserved for use by ICS.
Depending on the interface that is used, some of the MAC/Repeater
interface pins can also be no-connects. For pins that are no connects
when the interface is the:
– 100M Symbol Interface, see Section 9.3.4.2, “MAC/Repeater
Interface Pins for 100M Symbol Interface”.
– 10M Serial Interface, see Section 9.3.4.3, “MAC/Repeater Interface
Pins for 10M Serial Interface”.
Caution: Pins designated as ‘no-connect’pins must not be connected,
as connecting them can affect the performance of the
ICS1893.
