PROBLEM TO BE SOLVED: To obtain a multichannel timer capable of being small-sized and having a wide usability by providing a free running counter, a timer channel selector, an adding means and a control means. SOLUTION: The timer is provided with a free running counter 5, a counter 1 as a timer channel selector, an adder 6 for adding a value indicating timer setting period of a timer channel in case of receiving input signal of the channel to a value of the counter 5, a control part 4 to store the added result in a timer comparison register 3, a control part for outputting a coin coincidence signal when the added result read out of a memory means 3 coincides with the value in the counter 5 and distributes the coincidence signal to each timer channel, a comparator 7 and a decoder latch circuit 8. By this, constitution, at is made possible to be small-sized while loading a multitude of timer functions. |
