Abstract

A method (and apparatus) for determining, in a system including an m-bit time counter, whether an event-occurrence time lies after a predetermined timeout-value, includes reading out of a time-stamp memory a stored time-stamp value, determining the time-difference between the time-stamp value and the event-occurrence time, and determining whether the time-difference is larger than the predetermined timeout-value. The event-occurrence time is represented by a subset of the bits of the m-bit time counter, the subset being determined by a plurality of parameters including any two of a lower bit-position, an upper bit-position, and a subset width. The lower bit-position is dependent on the predetermined timeout-value.
