StartRCnt and so forth. But don't the counters just 'count' at a given rate, and you have to check them to see where they've got up to? I.e, they don't cause interrupts? The prog manual tells you about them but the library pages don't give enough info on what parameters they take. If they can cause an interrupt, that you be great, but AFAICT the only parameter the lib functions use is one that resets the counter to a set value.
