PURPOSE:To input a quick pulse string or a multipoint pulse string input by providing a counter circuit counting an inputted pulse string directly connecting the output of the counter circuit to the bus line of a processor such as a microprocessor. CONSTITUTION:The input pulse string 1 is inputted to the counter circuit 2, and sequentially counted and accumulated by the counter circuit. A microprocessor 4 appropriately transmits a read control signal 5 to the counter circuit, and reads and processes data accumulated in the counter circuit through a bus 3. The microprocessor transmits a reset signal 6 to the counter circuit the moment data reading ends, and the counter circuit is initialized. Thus a quick pulse string can be inputted and multipoints can be inputted. |
