a shift register group in which shift registers having a parallel data output function are cascaded to continuously hold a predetermined number of bits of input serial data;
A preset counter i that can be preset with arbitrary count data and that sequentially updates the count data by 1 by inputting a data read signal, and a preset counter i that can sequentially update the count data by 1 by inputting a data read signal, and a preset counter i that corresponds to the count data of this preset counter to a specific shift register of the shift register group. and a decoder that generates a parallel data output request signal, and is characterized in that serial digital data continuously input for a predetermined number of bits can be read out by specifying an arbitrary bit string for each shift register. Serial data input-parallel data output circuit.
