Unless you have a very strange architecture, it doesn't make sense for an interrupt to not be synchronous with the CPU clock. You are in the middle of an add instruction, and now you want to start an interrupt. What does that mean? I expect there is the standard 2 FF synchronizer on all the input pins. Things like the counter/timers run on the CPU clock, taking their input after the synchronizer. I don't remember seeing a data sheet that comes out and says that, but sometimes you can get some (strong?) hints with things like minimum pulse widths or max clock rate. -- These are my opinions.
