ICS1893 - Release

8.13.8

Link Loss Inhibit (bit 18.1)

The Link Loss Inhibit bit allows an STA to prevent the ICS1893 from dropping the link in 10Base-T mode.

When an STA sets this bit to logic:

• Zero, the state machine behaves normally and the link status is based on the signaling detected Twisted-

Pair Receiver inputs.

• One, the ICS1893 10Base-T Link Integrity Test state machine is forced into the ‘Link Passed’state

regardless of the Twisted-Pair Receiver input conditions.

8.13.9

Squelch Inhibit (bit 18.0)

The Squelch Inhibit bit allows an STA to control the ICS1893 Squelch Detection in 10Base-T mode. When

an STA sets this bit to logic:

• Zero, before the ICS1893 can establish a valid link, the ICS1893 must receive valid 10Base-T data.

• One, before the ICS1893 can establish a valid link, the ICS1893 must receive both valid 10Base-T data

followed by an IDL.
