(2) Accessory Output
The accessory output (RAUD pin) can carry either digital or analog output signals, and is controlled by address
0101 data bit D
4
(SW 8), and address 0111 data bit D
1
(SW 12).
When both SW 8 and SW 12 are in off position, the accessory outputline is in H-Z (high impedance) state. Caution:
never place both SW 8 and SW 12 in on position at the same time. This may cause the MB86434 to function
improperly.
