<p>PURPOSE:To shorten the calculating time of average value data by calculating average value data of an AD conversion data with an AD converter incorporated in a microcomputer with a hardware incorporated in the microcomputer. CONSTITUTION:The system is provided with the AD converter 1, an adder 2 adding AD conversion data, a counter 3 counting the number of adding times, a register 5 setting the N value of an N times average value, a comparator 4 comparating the value of the counter 3 with the register 5 to output an signal, a selector 6 selecting average data from the adder 2, a latching circuit 7 latching the output signal of the selector 6, and a control part 8 controlling the AD converter 1, the adder 2 and the counter 3.</p> |
