In tri-state input circuit 100, an input signal arriving at signgle input terminal 101 is supplied to two decision circuits of systems X and Y composed of CMOS; and in either circuit, e.g., system X, the input signal is discriminated on the basis of higher voltage VTH between two ...
PURPOSE:To reduce power consumption, obtain tolerance to variation in source voltage, and widen an in-use source voltage range by deciding on an input state sequentially by a timing signal, and holding the result in a storage circuit and outputting it as a 2-bit binary signal. CONSTITUTION:A...

But I can't find the option enable input tri-state on active configuration pins in user mode in Quartus II (9.1 sp2). Checking the Altera site, there is mentioned to add set_global_assignment -name tri_state_spi_pins on to the .qsf-file for Quartus II V10,...
