Note:
The Auto-Negotiation Progress Monitor consists of the Auto-Negotiation Complete bit (bit 17.4) and the
three Auto-Negotiation Monitor bits (bits 17.13:11). The Auto-Negotiation Progress Monitor continually
examines the state of the Auto-Negotiation Process State Machine and reports the status of
Auto-Negotiation using the three Auto-Negotiation Monitor bits. Therefore, the value of these three bits
provides the status of the Auto-Negotiation Process.
These three bits are initialized to logic zero in one of the following ways:
•
•
•
Hardware mode, the value of this bit is determined by the 10/100SEL input pin.
Software mode, the value of this bit is determined by the Data Rate bit 0.13.
Zero, it indicates that 10-MHz operations are selected.
One, the ICS1893CY-10 is indicating that 100-MHz operations are selected.
Hardware mode, the value of this bit is determined by the DPXSEL input pin.
Software mode, the value of this bit is determined by the Duplex Mode bit 0.8.
Zero, it indicates that half-duplex operations are selected.
One, the ICS1893CY-10 is indicating that full-duplex operations are selected.
