 The effect of this is that when the output bit is zero, all the bits in the register shift to the right unchanged, and the input bit becomes zero.When the output bit is one, the bits in the tap positions all flip (if they are 0, they become 1, and if they are 1, they become 0), and then the entire register is shifted to the right and the input bit becomes 1.To generate the same output stream, the order of the taps is the "counterpart" (see above) of the order for the conventional LFSR, otherwise the stream will be in reverse.
