Notes:
1. Both bIMR8 and bIMR4 devices are used in Minimum Mode.
2. The nformation displayed by Port Status LEDs s selected by SW1. In this design, only Link Status and Port Partition Status can
be selected. Users can implement more display options by changing the state of the SCLK input (see the section on Minimum
Mode for detail).
3. The Polarity correction feature is shown disabled since the SI is high at reset. Users can enable this feature by keeping the SI
input low upon reset.
