Hm, to be honest, I'm not so sure of what kind of efficiency we're speaking here. CPU time or memory? Probably both, right? Regarding the CPU efficiency, I would assume that this also dictates the maximum precision, right? Regarding memory we have probably different requirements: ROM for the whole thing, RAM per instance and for the module itself. > > Besides I'm missing a requirement regarding the maximum granularity and the > > maximum duration of a timer. > > You mean minimum granularity? In my understanding of the term maximum granularity translates to the finest granularity.
