7.3.12 Jabber Detect (bit 1.1)
7.3.13 Extended Capability (bit 1.0)
ICS1893CK-40, Rev. C, 06/02/09
The purpose of this bit is to allow an STA to determine if the ICS1893CK-40 detects a Jabber condition as
defined in the ISO/IEC specification.The ICS1893CK-40 Jabber Detection function is controlled by the
Jabber Inhibit bit in the 10Base-T Operations register (bit 18.5). To detect a Jabber condition, first the
ICS1893CK-40 Jabber Detection function must be enabled. When bit 18.5 is logic:

Note:
1. The Jabber Detect bit is accessible through both the Status register (as bit 1.1) and the QuickPoll
2. The Jabber Detect bit is a latching high (LH) bit. (For more information on latching high and latching low
The STA reads bit 1.0 to determine if the ICS1893CK-40 has an extended register set. In the
ICS1893CK-40 this bit is always logic one, indicating that it has extended registers.
Zero, the ICS1893CK-40 disables Jabber Detection and sets the Jabber Detect bit to logic zero.
One, the ICS1893CK-40 enables Jabber Detection and sets the Jabber Detect bit to logic one upon
detection of a Jabber condition. When no Jabber condition is detected, the Jabber Detect bit is not
altered.
Detailed Status Register (as bit 17.2). A read of either register clears the Jabber Detect bit.
