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.
