ICS1893CF Data Sheet Rev. J - Release

7.13.8 Link Loss Inhibit (bit 18.1)

The Link Loss Inhibit bit allows an STA to prevent the ICS1893CF 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 ICS1893CF 10Base-T Link Integrity Test state machine is forced into the ‘Link Passed’ state

regardless of the Twisted-Pair Receiver input conditions.

7.13.9 Squelch Inhibit (bit 18.0)

The Squelch Inhibit bit allows an STA to control the ICS1893CF Squelch Detection in 10Base-T mode.

When an STA sets this bit to logic:

• Zero, before the ICS1893CF can establish a valid link, the ICS1893CF must receive valid 10Base-T

data.

• One, before the ICS1893CF can establish a valid link, the ICS1893CF must receive both valid 10Base-T

data followed by an IDL.
