Start the POKEY timers (the AUDF registers above). You POKE any non-zero value here to load and start the timers; the value isn't itself used in the calculations. This resets all of the audio frequency dividers to their AUDF values. If enabled by [IRQEN] below, these AUDF registers generate timer interrupts when they count down from the number you POKEd there to zero. The vectors for the [AUDF1], [AUDF2] and [AUDF4] timer interrupts are located between 528 and 533 ($210 and $215) [VTIMR1], [VTIMR2], [VTIMR4]. POKEY timer four interrupt is only enabled in the new "B" OS ROMs.
