ICS1893 Data Sheet - Release

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.
