PURPOSE:To prevent the loss of detail information, by providing a command for permitting the registration of a detected error and a command for inhibiting the registration. CONSTITUTION:A detail information storage register 23 is stored with the identification code 202 of an error from an error detecting circuit 24 and address information outputted from an address register 22. In memory scanning operation, even if an error is detected in a command 101 from a central processor 1, its details are not registered in the register 23. In normal read/write operation, a command for setting the output 203 of a command register 21 to ''0'' is sent out to register the details of the error in the register 23. |
