Abstract

PURPOSE:To enable to output a plurality of arbitrary pulses, by representing time with free running counter FRC, sequentially setting the time to change the output to a compared register and comparing the set and counter values. CONSTITUTION:When an event is taken place, interruption is made to CPU7 of microcomputer, and the count value of a free running counter FRC 5 at that time point is read in. Simultaneously, the output S10 of an output port 8 is inverted. In a CPU7, the value corresponding to desired pulse width is added to the value read in and the result of operation is written in a comparison register 6 as a signal 8. The output of FRC 5 is increased, as time is elapsed and when it reaches the written-in value to the register 6, the register 6 outputs a signal S9 to interrupt the CPU7 and to invert the output S10. Accordingly, the output S10 is risen with the pulse S1 and has fall at the desired pulse width. By repeating this, when the output line of the port 8 is switched every occasion, a plurality of pulses can be picked up from a plurality of output lines.
