Editing POKEY (section)

==Features==
* Audio
** 4 semi-independent audio channels
** Channels may be configured as one of:
*** Four 8-bit channels
*** Two 16-bit channels
*** One 16-bit channel and two 8-bit channels
** Per-channel [[loudness|volume]], [[frequency]], and [[waveform]] ([[Square wave (waveform)|square wave]] with variable [[duty cycle]] or [[Linear feedback shift register|pseudorandom]] noise)
** 15&nbsp;kHz or 64&nbsp;kHz [[frequency divider]].
** Two channels may be driven at the CPU clock frequency.
** [[High-pass filter]]
* Keyboard scan (up to 64 keys) + 2 modifier bits (Shift, Control) + Break
* [[Potentiometer]] ports (8 independent ports, each with 8-bit resolution)
* High Resolution Timers (audio channels 1, 2, and 4 can be configured to cause timer interrupts when they cross zero)
* [[Random number generator]] (8 bits of a 17-bit polynomial counter can be read)
* [[Serial communications|Serial]] [[I/O]] port
* Eight [[Interrupt request|IRQ]] interrupts
