ables to configure which channels to output on PCM data. This is done through the register PL_DWN.
An auto-balance feature is available and activated through PL_AB register. The delay on surround channel is
configurable thanks to the LSDLY register (while resetting the RSDLY register).
The bass redirection is performed after the Pro Logic decode. The same bass redirection configuration than
those available in non-Pro Logic modes can be used except that the surround channels will not be added to the
bass redirection. In the case of AC-3 or MPEG the STA310 is therefore capable of first decoding the AC-3 or
MPEG stream then performing the Pro Logic decode.

4.8 How to choose a decoder
To set up the device you have to select two registers.
The first one is DECODESEL for Audio data type,
The second one is STREAMSEL for Transport data type,
The STREAMSEL can be set-up as follows:
So the possible configurations on listed in the following table:

- Karaoke system
- Bass Management + Volume Control
- Deemphasis
- DC Remove
