The tune might be single, but the filter setup would be different. In which case it wouldn't correct to do a reset of the counters ona tune. Resetting the counters should be the responsibility of the driver. As I said in an earlier post, anything other than the driver handling any statistical event monitoring, such an API is broken for sure, without even reading single line of code for that API for which it is written for. > OK, maybe we will see in near future if that works well or not.

With multi-standard demodulators, some of them PER compute is a by-product of some internal demodulator algorithmic operation. In some cases, it might require a loop in the driver. As I said, again; It is very hard/wrong to do basic generalizations.
