<p>PURPOSE:To attain the multi-channel constitution of a pulse output part by using a free running counter, a comparator and a comparison data storing register to form the pulse output part and also using the overflow of an FRC. CONSTITUTION:An output pulse part includes the free running counter 503, the register 501 which stores the data to be compared, the comparator 502 which compares the contents of the counter 503 with those of the register 501 and an output control part 504 which is set under the states opposite to each other by the coincidence signal of the comparator 502 and the overflow of the counter 503. An output pulse control part 400 interrupts the execution of a central processing part 101 with the coincidence signal of the comparator of the pulse output part while holding a state related with the program execution. Then the part 101 executes an action to store the data stored in a memory part 103 into the register of a pulse output part.</p> |
