Hi,
We need a simple timer which triggers SWBA interrupts. We know about the AR_TIMER0 ... 3 and the AR_BEACON timers. When we use AR_BEACON timer with AR_TIMER2, we get two SWBA interrupts - one immediately after TSF reset and one after the AR_TIMER2 time elapses (and after that we get periodic interrupts according to time set in AR_BEACON). We don't want an interrupt to occur immediately after TSF reset. Is there some way to acheive this? Due to our stringent time requirements we need to use hardware timer rather than software/kernel timers.  

Could you please point us to some reference/manual in which the working of Atheros timers is described.

Thanks and Regards
