Stratix IV OCT
When using calibrated input parallel and calibrated output series termination on
bidirectional pins, they must use the same termination value because each I/O pin
can only reference one OCT calibration block. The only exception is when using 50 Ω
parallel OCT and 25 Ω series OCT using the left shift series termination control. For
example, you cannot use calibrated 50 Ω parallel OCT on the input buffer of a
bidirectional pin and calibrated 40 Ω series OCT on the output buffer because these
would require two separate calibration blocks with different RUP and RDN resistor
values.
