Abstract : A serial to parallel converter receives a succession of digital bits in serial form comprising discrete data formats and control formats through its input terminal, which is coupled to a data shift register and to a control shift register. When a data format is coupled into the input, a register enable circuit enables the data register to load and convert sets of changeable data bits, comprising part of the data format, to parallel form. When a control format is coupled into the input, the register enable circuit enables the control shift register to convert sets of changeable control bits, comprising part of the control format, to parallel form. One of the changeable bits in every control format immediately followed by a data format comprises an incoming data indicator. During the period that a control format containing an incoming data indicator is being coupled to the converter, a register selector circuit responds to the indicator by instructing the register enable circuit that the next incoming format will be a data format.
