Abstract
PURPOSE: To make it possible to obtain directly up-to-data error information from error detailing registers by providing an error register for microprogram control information independently so that this register can be set together with detailing registers at the same time.
CONSTITUTION: Register 5 stores that error detector circuits 4 and 3 have detected and error. Meanwhile, detailing registers 6 and 7 are provided correspondingly to circuits 3 and 4 which are set by the same timing clock as register 5. Then, NAND circuit 14, 15, 18 and 19 inhibit detailing registers 6 and 7 from being reset by a microprogram, and simultaneously, reset detailing registers other than the detailing register corresponding to one error detector circuit, at least. Then, the state where one of registers 6 and 7, at least, is set and contents of registers 6 and 7 are displayed on displays 8 and 9. Thus, up-to-date error information can be obtained directly from registers 6 and 7 at an arbitray time
