Abstract
PURPOSE:To improve the through-put with a countermeasure to an intermittent failure, by avoiding the halt of self-diagnostic error which does not require the halt of micro mu program PG and making other devices informed of it. CONSTITUTION:The mu processor PC1 reads out the mu instruction code from the muPG memory 2 for command processing and self diagnosis processing and the like. If an error is detected during the self diagnosis of other hardware 5, the diagnostic retrial bit 41 stored in the sense information memory 4 is set and retried by n-times at the counter 42. If retrial is failed, the halt signal is fed from the halt register RG3 to PC1 for halt, and the halt is informed to other controller. If retrial is successuful, error display is set to the interruption status RG10 to PC1 and informed as the error. When the other controller reads in the error from RG10, the sense command is given to seek the cause of the error.
