ICS1893Y-10 - Release
Chapter 7 Management Register Set
7.12.1 Data Rate (bit 17.15)
The Data Rate bit indicates the âselected technologyâ. If the ICS1893Y-10 is in:
⢠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.
When bit 17.15 is logic:
⢠Zero, it indicates that 10-MHz operations are selected.
⢠One, the ICS1893Y-10 is indicating that 100-MHz operations are selected.
Note: This bit does not imply any link status.
7.12.2 Duplex (bit 17.14)
The Duplex bit indicates the âselected technologyâ. If the ICS1893Y-10 is in:
⢠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.
When bit 17.14 is logic:
⢠Zero, it indicates that half-duplex operations are selected.
⢠One, the ICS1893Y-10 is indicating that full-duplex operations are selected.
Note: This bit does not imply any link status.
7.12.3 Auto-Negotiation Progress Monitor (bits 17.13:11)
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:
⢠A reset (see Section 4.1, âReset Operationsâ)
⢠Disabling Auto-Negotiation [see Section 7.2.4, âAuto-Negotiation Enable (bit 0.12)â]
⢠Restarting Auto-Negotiation [see Section 7.2.7, âRestart Auto-Negotiation (bit 0.9)â]
