ABSTRACT:
A serial-to-parallel converter circuit comprising: an m-bit serial data holding unit to be input with serial data whose input bit number is set to m or n (<m) bits within a transfer period and a serial clock synchronized therewith, and to shift and hold the serial data by one bit based on the serial clock; an input mode identifying unit to identify whether the input bit number is m or n bits, based on a count value obtained by counting the number of generation of the serial clock during the transfer period; and a parallel data generating unit to output the held m-bit data as first parallel data when the input bit number is identified as m bits, and to output m-bit data obtained by adding predetermined (m−n)-bit data to the held n-bit data as second parallel data when the input bit number is identified as n bits.
