<p>PURPOSE:To easily set various states by mounting a rewritable read-only memory on modules of replacement units having the same circuit elements and making their contents different. CONSTITUTION:A replacement module 1 which constitutes a timing control circuit sends a timing start input 52 to a timing delay element 21 and a timing output 53 is obtained through a selector circuit 22 which switch the outputs of elements 21. A readout control circuit 12 reads the output of a read-only memory circuit 11 in order by being indicated by a readout control indication input 51 and inputs the read contents to an FF group 13 with a shift function. The FF group 13 to which the data is shifted and inputted become select inputs of the circuits 22 and indicate timing setting. The circuit is rewritable, so it operates speedily as a timing control module of different timing standard. Consequently, states by performance are easily set for other connection modules.</p> |
