ABSTRACT:
In a flag control circuit successively supplied with first and second input flag signals produced in relation to first and second results of calculations in an arithmetic and logic unit to produce a final output flag signal, the first input flag signal is latched by a primary flag signal latching circuit while the second input flag signal is latched by the secondary flag signal latching circuit. The first latched flag signal and the second latched flag signal are ANDed by an AND gate circuit to produce the final output flag signal.
