PURPOSE:To shorten the detecting time of an incorrect area through a data line monitor. CONSTITUTION:A date comparing part 6 compares the data on a date bus 1 with the data on a date bus 2 end stores the result of this comparison in a result register 8. Meanwhile, a data comparing part 7 compares the data on the bus 2 with the data on a data bus 3 and stores the result of this comparison in the register 8. Thus, it is possible to detect one of buses 1-3 that has the incorrect data by reference to the contents of the register 8. |
