Abstract
PURPOSE: To detect immediately the fault occurrence of a control circuit as to buffer memory BFM by providing a flag bit to each group of data stored in BFM, and then by supervising the flag bit by a central controller.
CONSTITUTION: Sense matrix SMX is read and right before data are stored in buffer memory BMF, flag bit FB is set to "1" at the initial address of write data W- DT. When FB of data R-DT read out from central controller (CC) is "1", it is considered to be correct data and a read process is advanced. Then, this FB is reset to "0" by reset circuit RS. Since the read period of CC is shorter than the write period of BFM, "1" can be read from FB all the time as far as a control circuit for BFM is normal. If this control circuit gets out of order, BF has a part where no data are periodically written and may become "0" in data read operation. In this case, error detection circuit ED provides fault detection.
