A data-processing arrangement (DPA) comprises an interrupt generator (IG). The interrupt generator (IG) carries out a count (CNT) of events (E) of a certain type (T1) occurring in the data-processing arrangement (DPA). The interrupt generator (IG) provides an interrupt signal (IS) when a predefined number (N) of events (E[T1]) have been counted. The interrupt generator (IG) comprises a programmable start-event selector (SEL[STRT]) for selecting a type (T2) of event (E) which starts (STRT) the count (CNT).Accordingly, there is no need for any controller to start the count and, consequently, there is neither need for a further interrupt generator nor for a special subroutine to make the controller start the count. Consequently, the data processing arrangement as summarized hereinbefore yields better efficiency either cost-wise or software-wise, or both. |
