7.12.4 100Base-TX Receive Signal Lost (bit 17.10)
7.12.5 100Base PLL Lock Error (bit 17.9)
ICS1893CF, Rev. J, 08/11/09
Note:
Table 7-19. Auto-Negotiation State Machine (Progress Monitor)
The 100Base-TX Receive Signal Lost bit indicates to an STA whether the ICS1893CF has lost its
100Base-TX Receive Signal. 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 Phase-Locked Loop (PLL) Lock Error bit indicates to an STA whether the ICS1893CF has ever
experienced a PLL Lock Error. A PLL Lock Error occurs when the PLL fails to lock onto the incoming
100Base data stream. 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”

Zero, it indicates the Receive Signal has remained valid since either the last read or reset of this register.
One, it indicates the Receive Signal was lost since either the last read or reset of this register.
Zero, it indicates that a PLL Lock Error has not occurred since either the last read or reset of this register.
One, it indicates that a PLL Lock Error has occurred since either the last read or reset of this register.
An MDIO read of these bits provides a history of the greatest progress achieved by the
auto-negotiation process. In addition, the MDIO read latches the present state of the
Auto-Negotiation State Machine for a subsequent read.
This bit has no definition in 10Base-T mode.
This bit has no definition in 10Base-T mode.
