3 V Single Power Supply Audio Interface Unit (AIU)

MB86435

(2) Accessory Output

The accessory output (RAUD pin) can carry either digital or analog output signals, and is controlled by address

0101 data bit D4 (SW 8), and address 0111 data bit D1 (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 MB86435 to function

improperly.
