8.12.8
Halt Symbol (bit 17.6)
The Halt Symbol bit indicates to an STA the detection of a Halt Symbol in a 100Base data stream by the
ICS1893.
During reception of a valid packet, the ICS1893 examines each symbol to ensure that the data being
passed to the MAC/Repeater Interface is error free. In addition, it looks for special symbols such as the Halt
Symbol. If a Halt Symbol is encountered, the ICS1893 indicates this condition to the MAC/repeater.
If this bit is set to a logic:
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.
This bit is a latching high bit. (For more information on latching high and latching low bits, see Section
8.1.4.1, “Latching High Bits”and Section 8.1.4.2, “Latching Low Bits”.)
Note:
This bit has no definition in 10Base-T mode.
8.12.9
Premature End (bit 17.5)
The Premature End bit indicates to an STA the detection of two consecutive Idles in a 100Base data
stream by the ICS1893.
During reception of a valid packet, the ICS1893 examines each symbol to ensure that the data being
passed to the MAC/Repeater Interface is error free. If two consecutive Idles are encountered, it indicates
this condition to the MAC/repeater by setting this bit.
If this bit is set to a logic:
Zero, it indicates a Premature End condition has not been detected since either the last read or reset of
this register.
One, it indicates a Premature End condition was detected in the packet since either the last read or reset
of this register.
This bit is a latching high bit. (For more information on latching high and latching low bits, see Section
8.1.4.1, “Latching High Bits”and Section 8.1.4.2, “Latching Low Bits”.)
Note:
This bit has no definition in 10Base-T mode.
8.12.10
Auto-Negotiation Complete (bit 17.4)
The Auto-Negotiation Complete bit is used to indicate to an STA the completion of the Auto-Negotiation
process. When this bit is set to logic:
Zero, it indicates that the auto-negotiation process is either not complete or is disabled by the Control
Register’s Auto-Negotiation Enable bit (bit 0.12)
One, it indicates that the ICS1893 has completed the auto-negotiation process and that the contents of
Management Registers 4, 5, and 6 are valid.
8.12.11
100Base-TX Signal Detect (bit 17.3)
The 100Base-TX Signal Detect bit indicates either the presence or absence of a signal on the Twisted-Pair
Receive pins (TP_RXP and TP_RXN) in 100Base-TX mode. This bit is logic:
Zero when no signal is detected on the Twisted-Pair Receive pins.
One when a signal is present on the Twisted-Pair Receive pins.
