Chapter 8 Management Register Set
8.12.1 Data Rate (bit 17.15)
The Data Rate bit indicates the ‘selected technology’. If the ICS1893 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 ICS1893 is indicating that 100-MHz operations are selected.
Note: This bit does not imply any link status.
8.12.2 Duplex (bit 17.14)
The Duplex bit indicates the ‘selected technology’. If the ICS1893 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 ICS1893 is indicating that full-duplex operations are selected.
Note: This bit does not imply any link status.
