PURPOSE:To attain time setting and change of a sequence signal by an external signal by providing each circuit performing clock generation, sequence signal setting, correction time input, correction time width input and sequence signal output, and a microcomputer. CONSTITUTION:Initial set is attained by the input of a start signal to start a clock generating circuit 11 so as to attain interruption of a reference clock. When interruption is applied, an output port is reset, number (t) of interruption of the reference clock is counted and when time collation is not conducted during the interruption, the content of an address (n) stored in a memory of a sequence signal setting 12 is read whether or not time correction is performed is discriminated. When no correction is performed, an output time Tn=t-tn is calculated by the setting time tn from the said address and when corrected, a time Tn=t+tv-Tn is calculated by a correction time tv. When T=0 is reached, an output signal 17 is outputted and the setting time tn is corrected properly by the external correction time tv signal. |
