7.12.6 False Carrier (bit 17.8)
7.12.7 Invalid Symbol (bit 17.7)
7.12.8 Halt Symbol (bit 17.6)
ICS1893CK-40, Rev. C, 06/02/09
The False Carrier bit indicates to an STA the detection of a False Carrier by the ICS1893CK-40 in 100Base
mode.
A False Carrier occurs when the ICS1893CK-40 begins evaluating potential data on the incoming 100Base
data stream, only to learn that it was not a valid /J/K/. If this bit is set to a 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”
Note:
The Invalid Symbol bit indicates to an STA the detection of an Invalid Symbol in a 100Base data stream by
the ICS1893CK-40.
When the ICS1893CK-40 is receiving a packet, it examines each received Symbol to ensure the data is
error free. If an error occurs, the port indicates this condition to the MAC by asserting the RXER signal. In
addition, the ICS1893CK-40 sets its Invalid Symbol bit to logic one. Therefore, if this bit is set to a 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”
Note:
The Halt Symbol bit indicates to an STA the detection of a Halt Symbol in a 100Base data stream by the
ICS1893CK-40.
During reception of a valid packet, the ICS1893CK-40 examines each symbol to ensure that the data being
passed to the MAC Interface is error free. In addition, it looks for special symbols such as the Halt Symbol.
If a Halt Symbol is encountered, the ICS1893CK-40 indicates this condition to the MAC.
If this bit is set to a 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”
Note:
Zero, it indicates a False Carrier has not been detected since either the last read or reset of this register.
One, it indicates a False Carrier was detected since either the last read or reset of this register.
Zero, it indicates an Invalid Symbol has not been detected since either the last read or reset of this
register.
One, it indicates an Invalid Symbol was detected since either the last read or reset of this register.
Zero, it indicates a Halt Symbol has not been detected since either the last read or reset of this register.
One, it indicates a Halt Symbol was detected in the packet since either the last read or reset of this
register.
