<p>PURPOSE:To make it possible to connect also an element with slow response time by providing a network with a data temporary holding circuit connected to that held data are outputted to a bus based on an access from a microprocessor or the like. CONSTITUTION:Data on a data bus 3 are acquired and held in the temporary holding circuit 10 for data with a small set-up time at the leading edge part of a data reading signal 4. When an access signal 6 to the circuit 10 is outputted from the microprocessor 1 or the like, the circuit 10 starts to output data held in the data bus 3. Since the microprocessor 1 or the like sufficiently satisfies the set-up time, accurate reading can be attained. Namely, the microprocessor 1 or the like reads out data from an element 2 with a slow response time at first, deletes the read data and then reads out data from the circuit 10 to treat the data as the one obtained from the element 2.</p> |
