Hi,
I'm working on a design that couples together PCM3070 and TAS5708. I'm utilizing both I2S and line outs of PCM3070.
I'm using the 8x4x framework
FS = 48Khz
CODEC_CLKIN = 86.016Mhz
NADC, NDAC = 2
MADC, MDAC = 7
AOSR and DOSR =128.
I'm having trouble finding the right values for "Instruction Control Registers" (Page 0 Register 15, 16 and 21, 22). Some numbers seem to magically work for a generated code, while others don't. The only constraint that is mentioned on the Application Reference Manual is that they have to be a multiple of decimation factor (4) and interpolation factor (8) , but that doesn't seem to be enough.
Any clues on what they stand for and how to come up with the right values for them is greatly appreciated.
Regards
