<p>PROBLEM TO BE SOLVED: To provide a sequence controller which can surely detect an event that occurs in a short cycle to process it within its cycle and also can execute even the processing of a long cycle event by the same circuit. SOLUTION: A sequencer circuit 10 sequentially produces the address signals 102 is every cycle of 125μsec and provides these signals to a memory circuit 12 to read out one block of a statement which receives a reference clock 100 and processes it in a cycle of 125μsec, a statement which processes the clock 100 in a cycle of 10 msec and a statement which processes the clock 100 in a cycle of 100 msec respectively. The circuit 12 previously stores the statements and reads out a statement 104 according to an address signal 102 to provide it to a decoder circuit 14. The circuit 14 decodes the statement 104 and produces a control signal 106 to provide it to a switch circuit 16. Thus, the circuit 16 controls the function register circuit 18 to 22 according to the signal 106.</p> |
