7.3.12 Jabber Detect (bit 1.1)
7.3.13 Extended Capability (bit 1.0)
ICS1893BF, Rev. F, 5/13/10
The purpose of this bit is to allow an STA to determine if the ICS1893BF detects a Jabber condition as
defined in the ISO/IEC specification.The ICS1893BF 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 ICS1893BF
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 ICS1893BF has an extended register set. In the ICS1893BF this
bit is always logic one, indicating that it has extended registers.
Zero, the ICS1893BF disables Jabber Detection and sets the Jabber Detect bit to logic zero.
One, the ICS1893BF 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.
