Write#
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.see also: Keyboard topics Console Keys HELP
