4.9 How to Program a Post Processing

4.9.1 2 registers for the mode:

PDEC (0x62) to define the type of PostProcessing

4.9.2 1 or 2 registers to control the “PostProcessing”

Prologic decoder (PDEC = 0x01):

Remark: When playing “Dolby Digital Prologic encoded”, if PL_DOWNMIX is correctly set, Prologic decoder’ is

automatically applied even if the register “PDEC” different to 1.
