8.13.8 Link Loss Inhibit (bit 18.1)
8.13.9 Squelch Inhibit (bit 18.0)
ICS1893 Rev C 6/6/00
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:
•
•
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, 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.
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.
