AUDCTL is the option byte which affects all sound channels. This bit assignment is:
||Bit||Description
|7| 0=17 bit poly counter \\1=9 bit polynomial noise
|6| 0=clock channel 1 with 64kHz\\1=Clock channel one with 1.79 MHz (NTSC) or 1.77MHz (PAL)
|5| 0=clock channel 3 with 64kHz\\1=Clock channel three with 1.79 MHz (NTSC) or 1.77MHz (PAL)
|4| 0=clock channel 2 with 64kHz\\1=Join channels two and one (16 bit, with 2/4=MSB, 1/2=LSB)
|3| 0=clock channel 4 with 64kHz\\1=Join channels four and three (16 bit, with 2/4=MSB, 1/2=LSB)
|2| 1=Insert high pass filter into channel one, clocked by channel two
|1| 1=Insert high pass filter into channel three, clocked by channel four
|0| 0=main clock base 64 KHz\\1=16 KHz main clock base

||Bit||Paddle
|0|Paddle 0, [PADDL0], [POT0]
|1|Paddle 1, [PADDL1], [POT1]
|2|Paddle 2, [PADDL2], [POT2]
|3|Paddle 3, [PADDL3], [POT3]
|4|Paddle 4, [PADDL4], [POT4]
|5|Paddle 5, [PADDL5], [POT5]
|6|Paddle 6, [PADDL6], [POT6]
|7|Paddle 7, [PADDL7], [POT7]
If a bit is set to zero, then the register value for that pot is valid (it's in use); if it is one, then the value is not valid.
Shows if the readings of the pots are (already) valid.
||Bit||Paddle||Shadow||Register
|0|Paddle 0| [PADDL0]| [POT0]
|1|Paddle 1| [PADDL1]| [POT1]
|2|Paddle 2| [PADDL2]| [POT2]
|3|Paddle 3| [PADDL3]| [POT3]
|4|Paddle 4| [PADDL4]| [POT4]
|5|Paddle 5| [PADDL5]| [POT5]
|6|Paddle 6| [PADDL6]| [POT6]
|7|Paddle 7| [PADDL7]| [POT7]
If a bit equals zero (0), then the register value for that pot (e.g. Bit 0 = [POT0]) is valid; if the Bit is one (1), then the value is not (yet) valid, because the reading/scan is not finished yet or there is no paddle connected.
