Description of the audioprocessor

IN/OUT control
IN/OUT control offers selectable full-differential stereo input or Bass output as figure15
shown. When used as full-differential input, bass buffer output is disabled, full-differential
input switch sw1(sw4) closes and sw2(sw3) closes. When used as bass output, full-
differential input switch sw1(sw4) opens and sw2(sw3) still closes, single ended bass output
signal is converted to full differential output. IN/OUT control supports high impedance status
when bass buffer output is disabled, full-differential input switch sw1(sw4) opens and
sw2(sw3) closes.

Audioprocessor Testing
In the test mode, which can be activated by setting bit D7 of the IIC subaddress byte and bit
D0 of the testing audioprocessor byte, several internal signals are available at the QDL pin.
In this mode, the input resistance of 100kOhm is disconnected from the pin. Internal signals
available for testing are listed in the data-byte specification. External clock can be available
at the SE1R pin.
