7.13 Register 18: 10Base-T Operations Register
The 10Base-T Operations Register provides an STA with the ability to monitor and control the ICS1893BF
activity while the ICS1893BF is operating in 10Base-T mode.
Note:
1. For an explanation of acronyms used in Table 7-20, see Chapter 1, “Abbreviations and Acronyms”.
2. During any write operation to any bit in this register, the STA must write the default value to all
Reserved bits.
7.13.1 Remote Jabber Detect (bit 18.15)
The Remote Jabber Detect bit is provided to indicate that an ICS1893BF 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:
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.
One, it indicates a Jabber Condition has 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 a latching high bit. (For more information on latching high and latching low bits, see Section
Note: 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 ICS1893BF port monitors its receive path and applies the ISO/IEC Jabber criteria to its receive
path.
