7.13 Register 18: 10Base-T Operations Register
7.13.1 Remote Jabber Detect (bit 18.15)
ICS1893CK-40, Rev. C, 06/02/09
The 10Base-T Operations Register provides an STA with the ability to monitor and control the
ICS1893CK-40 activity while the ICS1893CK-40 is operating in 10Base-T mode.
Note:

Table 7-20. 10Base-T Operations Register (register 18 [0x12])
The Remote Jabber Detect bit is provided to indicate that an ICS1893CK-40 port has detected a Jabber
Condition on its receive path. This bit is reset to logic zero on a read of the 10Base-T operations register.
When this bit is logic:

•
This bit is a latching high bit. (For more information on latching high and latching low bits, see
7.1.4.1, “Latching High Bits”

Zero, it indicates a Jabber Condition has not occurred on the port’s receive path since either the last read
of this register or the last reset of the associated port.

This bit is provided for information purposes only (that is, no actions are taken by the port). The
ISO/IEC specification defines the Jabber Condition in terms of a port’s transmit path. To set this bit,
an ICS1893CK-40 port monitors its receive path and applies the ISO/IEC Jabber criteria to its
receive path.
