AUDCTL (Write)#

AUDCTL is the option byte which affects all sound channels. This bit assignment is:

Bit	Description
7	Makes the 17 bit poly counter into nine bit poly
6	Clock channel one with 1.79 MHz
5	Clock channel three with 1.79 MHz
4	Join channels two and one (16 bit)
3	Join channels four and three (16 bit)
2	Insert high pass filter into channel one, clocked by channel two
1	Insert high pass filter into channel two, clocked by channel four
0	Switch main clock base from 64 KHz to 15 KHz to be done

ALLPOT (Read)#

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.
